I recently tried to open limewire and found the limewire icon had now turned into the limewire icon with an exclamation mark embedded in a yellow triangle. Now when I look the icon it has the "users" icon laid over it. I am concerned about this glitch in my gui. Anything at all would be helpful.

At a guess, I'd suggest anything with an exclamation mark means the original file has been moved or permissions changed or user accessibility changed. See the following:
