Ok I get a different message saying

"One or more necessary files appear to be invalid.
This is generally caused by a corrupted installation.
Please try downloading and installing LiveWire again...... and so on"

but when I try to download Limewire again it asks me to unistall the Limewire thats already on my computer and half way through that it gives me another error message saying it couldn't finish uninstalling cause something was missing or something was corrupted can anyone help with that?
