Limewire Wont Run
 

I have had limewire for 6 months now. Worked fine, no problems. Everytime I turn on the computer it automatically connects to limewire. All I have to do is click the round lime shape in the corner by the time to start it up. Then it usually has its tips pop and says update to limewire pro, then I usually serach for a song or something. Now when I click on the round lime in the corner it just shows me the tips and such but not the program itself. It wont open/run and I cant download anything even. If I reinstall it would delete all my songs? What could be the problem of my computer not opening it up? Thanks.
