Can't load into Aurum Vale Duty

[Jojoya]

I've tried updating the graphics card, several times over several months as well.

There isn't an easy to find option to scan and repair through the FFxiv launcher, but if it helps, my graphics card is a NVIDIA GeForce GTX 1060 6GB.
I seem to not think it's a graphic issue simply because I can do Heavensward and Stormblood dungeons without any issues at all. This is the only dungeon, where it's stopped me from progressing further into the Grand Company. Maelstrom if it helps.

Far more likely that it's a corrupt game file than some other issue with your PC.

First thing to check would be your character specific files, especially if you can enter Aurum Vale on your other character that you mentioned (assuming it's a high enough level). Save a copy of your character's folder to a different location on your PC then delete the original. Log into your character - the game will automatically create a new folder and character setting files though everything will be set to the game default. Try entering Aurum Vale solo unsynced.

If you can get in without issue, you'll know the corrupt file was one of the character files. You can choose to either restore all your character settings manually or copy back some of the files from the duplicate folder you created. Files with obviously descriptive names (like Gearset) should be safe enough to copy back though I'd avoid copying any of the files with less helpful names. If you restore any of the old files, enter Aurum Vale one last time to make sure you didn't reintroduce whatever was corrupted.

If you still can't get in after deleting the character folder, some other game file is corrupted. You'll probably need to do a full game re-install though you may want to open a thread in the Technical Support forum first to see if there are other things to check.

In that case, it is probably not a graphics issue but a file corruption/error issue caused by something missing/and or being broken in your current FF14 install and the game not fixing or detecting it.

It was indeed a corrupted game file, I only started playing last year and installed the game with my 'middle of nowhere swampland' internet. What would normally take a few hours to reinstall would take days. I travelled to my parents' and downloaded it there. First thing after installation was que immediately into Aurum Vale, and I had no issues whatsoever. There must have been a hiccup for that specific dungeon because I had no issues with the rest of the game thus far.

Thanks all for the help, pretty funny how this turned out.
