Error message

Tue Feb 8 13:22:51 EST 2011

The following error message pops up even when I do not have Pidgin running.  What do I need to do to fix this problem.  Pidgin appears to be working as I am able to receive IM's and can also send IM's.  I'm wondering if this error message has more to do with the computer settings and Pidgin or the IM server[s] and Pidgin.  Currently Pidgin is interfacing with 5 different IM's and Facebook chat.  
Any advise will be appreciated.  

    Error Changing Account Info

    Error 0x0001: Unable to format username because the requested name differs from the original.

Thank you for your assistance ...
