thanks for the BFU program. It uninstalled some programs. Unfortunately, whenever the progress bar arrives at the halfway mark, the entire program freezes and i have to restart it. Here's some more information if it helps:
The BFU freezes when it tries to delete file- Zeno
Here's what the Limewire error message says exactly:
"One or more necessary files appear to be invalid. This is generally caused by a corrupted intallation. Please try to download Limewire again"

Sorry, I don't know why the BFU would be freezing. Try updating your AV, scan your computer & then try with the BFU again if necessary. if you don't have an AV program, these three are all free.
