Last night I had to force shut down my MBP because my mail application didnt want to close. I had force shut down before with no problem and it let me log in the next time. Today when I try to log in it would take awhile then it would send me back to the page where I choose the accounts. While trying to log in, a box popped up saying that I had force shut down due to to my mail application and it ask would I want to turn it back on and I click yes. Still it wont let me log into my account. I am currently using my Guess account. Please Help! My warranty happen to just end a couple weeks ago. Apple is trying to set me up or something.
