Okay... lemme make sure I am getting all of this:
She is running WinME
Her mic isn't working, and brought up a message for Wglsp.dll
can hear you just fine
It sounds like it could be a few things, depending on the software, it could be a bad *.dll considering that the only reference I've seen for it wsa wingate, that sort of fits with the fact it's internet chat, or it could be completely unrelated, and it's just the Mic is incorrectly set up.... to be sure which one it is... what software are you using to talk? Does the mic work for anything else? Windows sound recorder
Start ->Programs -> Accessories -> Entertainment. If it works there, it's probably just the software, and she sould re-install, if not check back, I have a few more ideas. We'll get this taken care of.
