thx for the answer.

point 1. I already tried this one. Doesn's work. Some players don't even play the file others cancel after 20 seconds. And if I click on "Preview" Limewire tells that there was nothing to preview.

point 2. I deleted my .limewire but that didn't change anything

point 3. Limewire doesn't consider my file as corrupted so it doesn't attempt to redownload the file or hash tree or whudd eva.
What's that hash tree thing anyway?

But even it didn't work thanks!
