Gnutella Forums - confused

I had an issue with Limewire, so I ended up attempting to uninstall it. After doing so, I was getting this weird message (which I pasted to the bottom), and now I cant even install Limewire again. Each time I try it says that it is already running in the background and I need to stop the program. I do not know what to do and am looking for assistance. Thanks.

LimeWire version 4.12.6
Java version 1.5.0_09 from Sun Microsystems Inc.
Windows XP v. 5.1 on x86
Free/total memory: 3270104/4128768
