Error message when attempting to download
 

I am running Apple's OS 10.3.6 on a PowerBook G3, with LimeWire 4.2.6. When I try to download a song, the download does not even start and I get the error message:

LimeWire cannot open a necessary file because the file name contain characters which are not supported by your operating system. LimeWire may behave in unexpected ways.

Looking through the forum, someone with Windows had a similar problem, so I tried to include more languages (US English instead of just English, etc) in my International setting in my personal section of system preferences - it didn't work. Please help!
