Yes, just blame the Internet for your lack of research before buying Pro. Like e.g. maybe trying to see if the free version would install on your comp.

And BTW Limewire should be possible to install on whatever computer given that the computer had proper software installed beforehand and was configured correctly.

Don't get me wrong here. I too believe that Limewire isn't a very good program, but by that I mean the program itself, not not being able to install it.
