Just the file library and when I type in the search for a song it's weird. It's in an unreadable font like Greek. Any way to solve this?

Are all LW's tabs & buttons in a different language as well? If so, try changing language.

If you're using LW 5 click here: http://www.gnutellaforums.com/genera...-language.html

If only some of LW shows in the weird language, did you try reinstalling Java as in post #2?
