limewire pro wont install
 

I downloaded limewire pro to rid my screen of the banners, and it wont install. whtas more the application that i have left is slow to respond to the point that it takes several seconds just to move a scroll bar. anyone help?
i should warn you that oi know next to nothing about computers and geek stuff so please keep it simple. oh yeah while i'm here. how do i put music files up for grabs. as i say, any help would be most gratefully received.

installing limewire pro for OS X
 

I'm also unable to install limewire pro for OS X. It downloads then simply switches me to microsoft word and then nothing

I downloaded the pro version and can't install it. The installer icon is generic and when I try to use it it says there is no application available to open it. I tried the free version first before the pro version with the same result. I'm using system 10.1.4 on a Powerbook G4. Any suggestions?
