This is really dumb...

I continually see these pop-ups with numbers that look like xxx.xx.xxxx.xx for example, and username/password.

What are these and what do I do?

I'm still really confused though, does anyone know what they are? I type it in sometimes and I get nothing.

I think until it's fixed, just close the windows out. There is nothing to input, as LimeWire requires no username/password in the first place. So, what would one enter anyway?

I had that and stupid me paid for LimewirePro which is NO better or different than the free version. Just click ok or cancel, whichever works and don't do what I did - unless you have money to throw away...
