Hi, when i try to sign into Windows Live, i can log in and like 2 seconds later it freezes, and it says program not responding, blah blah blah so all i can do is too exit and, i've tried repairing, uninstalling and reinstalling, rebooting and even resetting the modem.

i can sign into my friends and familys accounts, all but my own.
i got my friend to logon mine at his house and it worked perfectly.

i googled it and other peoples solutions dont work for me, anyone help? :c

Running Windows 7.
