Don't know how this will affect your Pro version, but there's 2 things you might try.
Delete Limewire, then re-install. When I installed limewire (basic) there was an option of wether to install Limeshop or not. I didn't.
Or run Ad-aware, which deletes spy and adware from your registry and hard drive. They have a free basic version you can get at:

Either option ought to work for you.
Have a Blast.
