Limewire stopped working properly so I uninstalled and reinstalled it but still didn't work. I have now uninstalled it again but i now get a window popping up on my desktop saying

"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 the problem persists, please visit Lime Wire » Official Website & Free Download, BitTorrent « and click the 'support' link.
Thank you.
(then in the box below this message i get the following report)
