confused and need a little help

[whiplock]

ok here's the situation. at the login screen i type in my login and password once i hit enter i see the server select screen for just a second then crash back to desktop. no error message or anything. everything was fine like 2 weeks ago. nothing has changed. just for troubleshooting purposes i reinstalled Titanium and tryed loggin in again. No go. still the same problem as mentioned above. so now im thinking since i havent been on for about 2 weeks could my login account have been wiped? so i create another login and try login to the server. Bam it works. so would it be possible that my account was wiped? if so how can i get it back? thanks for any help.
