Application Not Responding
 

I have downloaded several different versions of Limewire several times and they are all installed on my computer. No matter which version I click on, Limewire loads but as soon as the Upgrade to Pro button comes up, and sometimes even before, Limewire doesn't respond and it takes me minutes before I can even close Limewire. When I finally am able to close Limewire Internet Explorer doesn't work and I have to force quit that too. Then everything works fine... except for Limewire of course. Limewire worked fine until a couple of weeks ago :( Please help!!
