LimeWire uninstalling itself
 

I recently purchased a new computer with XP SP2 OS. I downloaded the latest version of LimeWire, ver 4.9.37. NOTE: I was using this same version on my old computer running ME.
Anyway, everytime I shut down my computer, I loose my LimeWire and have to reinstall. It works great, but hate to have to keep reinstalling and setting everything.
