[Jessinfrance]

Hi. I am in a bit of a state here and really need someones help !!

I bought a new Dell Laptop some weeks ago and am using Vista home premium. I dowloaded Limewire free, the same day and was getting a message coming up every minute or so saying that one or more files are invalid. I did not think to ask here for help and after failing to uninstall properly (the message kept popping up) I did a system restore and the message stopped !!

Today I was brave and downloaded Limewire again and the same thing is happening !! Please please please can someone help me sort out this problem XX!!

I have copied the error message

LimeWire version 4.16.6
Java version 1.6.0-oem from Sun Microsystems Inc.
