Wow ... I thought I was going crazy. Issue with characters? I mean I have letters and the number "4" and it is not working consistently. Very bizarre issue for sure ...
same issue here. Error message just stared a couple days ago. I have no special characters in my name or password. Kept trying and finally got in. I did also log in to yahoo messenger on my PC and on my ipod touch and they worked fine. I also made sure to log out of each and then tried bb and finally got in.
