Invalid files caused by corrupted installation
 

Limewire 4.14.10
Java 1.6.0_03 Sun Microsystems
Windows XP 5.1 on x86
Free memory 31 245 696

Message is:
One or more necessary files appear to be invalid; this is generally caused by a corrupted installation. Please try downloading and installing Limewire
again. If it persists, visit Limewire and click the support link.
When I try to download, it tells me to erase to the former installation; I
cannot erase every folder because thay say someone else is using the program; I've done a search and cannot find any other folder elsewhere. I tried downloading from different sources but the results are the same.

Can anyone out there help me ?:)
