Intermittent error when using an IM

Hi,
I just installed an Instant Messenger when I got this error message. The IM seems to be working fine, and I got this error intermittently (see screenshot below). I have searched the web and learned that I just have to uninstall the program.
However, I needed this program and wasn’t sure about the suggested resolution.
I hope an expert from this site can help address this problem.
Thanks in advance.
