I'm not sure if this has ever been covered before but I had to uninstall my LimeWire and this was before I installed it again and I got this message:

One or more necessary 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 limewire.com and click support link.
