quits when "download" is clicked

I originally posted this under upload/download problems, but maybe this would be a better area. I've had Limewire on my Mac OS 9.1 since May, and it's been mostly very functional.A couple of days ago, however I opened Limewire and it seemed to be working (except for the fact that all my incomplete downloads were gone) until I clicked the download button, which caused it to immediately quit (with no error message of any kind). I opened Limewire again and was able to search but when I clicked the download button it immediately closed the program. Since then I've tried a few things (updating to 3.6.15, restarting numerous times) and it has no problems opening or with any of its other functions, but every time I try to download it instantly closes. Anybody else seen anything like this?
