Gamebreaking, stuck in loading instance and stuck in main storyline:Titan Normal Mode

Thread Title: I'm not sure if this has been reported anymore after the first major update around August 25th~28th somewhere where most of the similar reports seem to be around. I'm now stuck in the game and can't continue the main storyline as I'm getting stuck in a black loading screen when trying to enter Titan Normal Mode fight in the Lord of Crags quest. A small loading icon in the lowermost right hand corner still ticks along as it normally does. I can still chat with my fellow instance mates. It doesn't seem to resolve itself when I'm trying to enter with different criteria like mounter or not, in what area I am and such, even what level job I'm entering with.
If I shut down the game while stuck in loading screen I can't re-enter for a while, until the instance has been shut down by going out of time or if my teammates managed to win and thus shut it down. So I can't enter the instance in any way as I see it right now.

ISP: Telia
Type of Internet Connection: DSL I believe.
Modem maker/model number: Didn't seem to matter as I've gotten the same problem for 2 different routers and modems. Tried both cable and wireless.
Internet Connection Speed: about 10~15down 10up Mbit/sec
Date & Time: No specific time as it happens whenever I try. GMT+1
Frequency: Always

Character Name: Ryax Ehreza
Race: Mithra/Miqo'te Female
World: Cerberus
Class/Level: Pugilist & Monk between 34 and 38
Area and Coordinates: It doesn't matter where I am when I do it. Done it in Coerthas Highlands and Ul'dah
Party or Solo: Duty Finder Light Party
NPC Name: None
Monster Name: None, just about to battle Titan however though I don't think that specific matters currently
In-Game Time: Any time
Steps: I've been running with mount, standing with mount, running with character and standing with character. Step one is just to enter Duty Finder and get a group for Titan Normal Mode and enter.
When entered and Light Party popped up, the screen remains black and the little loading icon shows at the bottom right hand side of the screen. I can chat with my instance party. Other sources seem to have been blocked out, like FC or LS. I haven't gotten any error message from this yet, even if staying for about 7 minutes on trying to load it.

I'd be very delighted if you could return to me with any way of bypassing the situation, at least for the moment, perhaps getting me past the fight at least so I can continue the rest of the storyline, or if you could advice me of any way that I could try to make it work anyway, say changing my graphics settings if they could be a problem.

Thank you for taking the time to look at this, I hope you return with an answer soon!

Greetings,

Thank you all for your posts concerning this issue. It appears that this issue may be a technical issue rather than an actual bug. As such, I will be moving this thread over there so that you can gain the proper assistance and an appropriate solution for your specific case. Thanks again!

I've tried to alter my graphical settings when entering, to see if they could affect the loading in any remote possible way. Seems not as the problem still happens even if I set everything to lowest and turn off everything unnecessary. It still won't give me an error on the loading either and wont let me return until the dungeon/instance is finished.

Now I just unlocked The Sunken Temple of Qarn, and the problem seem to be happening there as well as I got stuck in a black loading screen, little loading bar ticking along in a very non-fluent way, it kind of stutters along as it always does. I had to exit the game forcefully by alt-f4, though it doesn't close still. Though that seems to be a common problem since the latest big patch and it's not game breaking so I don't really mind.

Now I must say that I downloaded the game to my secondary drive. Would that have any implications to this? I'm going to try to uninstall it from my secondary drive and reinstalling it on my main drive instead to see if ti works. It bothers me to grrrrreat lengths that I can't progress in the main storyline because of load malfunction.

Is there ANYTHING that I can do to help you guys figure out the cause of the problem, like store a type of log or minidump somewhere? Again, is there a way that you could let me pass the titan fight at the very least so that I may progress in the game again?

So I went ahead and uninstalled my copy of the game, downloaded the client from the website and installed it though that and redownloading all of the required files. I installed it on my Main Drive(C:) this time as opposed to having installed it on my Secondary Drive(D:), and now I could fight Titan NM and progress in the storyline. I haven't tried The Sunken Temple yet, but at least now I'm happy that I can progress again, over 10 levels over the main target level for the storyline :) Makes things a lot easier and quicker though.

Thank you for your time in investigating this! I'll be back if there's anything else regarding this issue.
