LW StubInstaller
 

i saw this .exe called " StubInstaller " on C drive, I opened it and it like auto updates Limewire.. is that wut its made for? should i delete it, ? i have limewire pro 4.9.23, but after i opened the .exe It updated limewire to the basic one 4.9.30.. should i leave it alone , and just use limewire .. or install pro again? i really hate that pop up

You can get the 4.9.30 Pro update from you personal download page. But for some reason I have the feeling you do not have the personal download page.
