Application has encountered a critical error?

[Hippo]

Hi when I log in I get this message and then get kicked out, has anyone came across this before? I was playing wow about 10 hours ago and did nothing to my computer, then all the sudden when I logged in it gave me this error. Thanks for any help.

Here is a few steps I take when this used to happen to me ;)
. Try update graphics drivers, I know that 2.4.3 support ended a lllooooonnggggg ass time ago, but sometimes this can actually help and in some cases could improve FPS.
. Try deleting the "Cache" folder in your "World of Warcraft" folder, this can sometimes stop the application from crashing.
. If they don't work, try posting the "critical error report" here, usually the reason why your game is crashing is listed there ;)
You can find the report by pressing the "More Information" or "Details" tab that appears when your game crashes.

Good luck and post back your results here ^__^

Are you by chance logging into a character that was an old donor that had the old donor titles?

This is a long-shot but I had a problem like this when I was using Vista and fixed it by running WoW as an administrator. >_>
