Was working fine. Then wow encountered a problem and crashed. Tried to restart and kept getting the max sessions error. Restarted computer and now im getting this error.

Now im just getting authentication failed

 

now its saying invalid instance of wow selected, both running as administrator. its a new damn error every time i try to use it....

 

Are you running in DX9 mode and 32bit?

 

honestly I have no idea. I think 32 because it said start wow manually to use 32 and I did. but i dont see why it would work then wow crashes and now its not when i changed nothing. How do I use dx9 or run in dx9? Thanks for any info.

 

ok yes wow is running in 32bit. and was when i tried starting it.

 

ok now its working. but i have no idea why

 

Alrighty I installed. I post here again if it fixes it / didnt work the next time I used it. Kinda scared to restart it now in case it doesnt work. Going to try to get to 90 before I do lol.
