I can't access my instant messengers... they were working fine yesterday. I use Yahoo messenger and Windows Live messengers. Whenever I log on YM, it tries to log me in but gives me a 'sign in error' after a while. The error message tells me to check my username and/or password. I'm positive I input the right username and password tho. As for Windows Live, it just freezes with a blank interface after I sign in. I had to close it using Windows Task Manager.
Any ideas? I thought of reinstalling both but I googled about this problem. People tried reinstalling numerous times without much success.
Anyway, any feedback is much appreciated.
