Can you take out half your memory, try to run then take that half out and put the first half in and try to run.
This at least should eliminate ram as an issue.
Also Run fixlauncher.exe and the repair on the launcher
Tiandrah here...for some reason the system is now telling me I can't reply to my own posts now. Hate these stupid forums sometimes.
I still fail to see how too much memory could be a problem. But, I did take one stick of memory out and try it, and then the other. Still having the same issue. I've run fixlauncher, delted files, repaired things with the setup download....still not able to get in at all. Just constantly kicked out to the desktop before I ever get to the character screen.
