Any help is appreciated. If I need to provide more information, please let me know,

I'll just say you're not the only one with this... Happened to me at Ul'dah and when entering Ifrit yesterday.

I do have some random crashes as well.

Now I got a crash while trying to pick a leve... Just like I did 30min before the crash. Y SO RANDOM?!

I think there isn't anyone who doesn't have this issue. The client is very unstable. Well the servers are very unstable too xD

This happened to me for the very first time in Gridania the other day. I was just walking around and *bam* c0000005 crash. Perhaps these crashes happen when something goes to load and for whatever reason it fails or errors. They seem to happen more often in towns than out in the field, and we all know how much heavier on loading towns are :(

This has been happening to me all day today. It has happened before, every now and again, but this time it's like every 5-10 minutes, it crashes at random with no warning. Just a moment ago, it crashed, I booted it back up, and it crashed again at character selection.
