problem (can't click, files suddenly being shared)

Can someone tell me whats wrong with my limewire? I have had it for really long time never had any problems until about yesterday. I dont know if i got a virus in it to make it not work or not. It will open but i can not click on anything inside limewire. I also had all my music to where it wasnt to be shared and now all are able to get shared. I have done all i can think of to fix these problems but nothing has helped. any one got any suggestions or know what might be wrong?
