It might be best to remove the old version and try the new version 1.7.
The download is located in "LimeWire Beta Program" at the top of the page in LimeWire forums
Lots of problems in the older versions are addressed in the latest 1.7.
I'm using 1.7 now and it has some great features - including chat!
But we need more people to d/l it so we
can chat.
Good luck with the new one. If it don't work, come back on this thread and post again.
