Napster Is Blocking My Downloads.
 

Everytime I click "Save" to a song or movie etc. on Limewire, the Napster window pops up. So I uninstalled Napster and its still happening.

It sounds to me like you didn't uninstall Napster properly. Reset defaults to LW or else, ... get this gadget & clean up your registry & then reinstall LW (LW will uninstall itself at beginning of installation!): http://www.ccleaner.com/ will help clean your system. Just beware of a menu advert.

Okay I did that and it still comes up.

2 very trustworthy utilities to check with: 1. ad-ware (FREE), & also 2. Spybot - Search & Destroy (FREE)

We always recommend these 2 to users & they can be trusted! If still problems, post your problem in the General section of Norbie's site & see what he thinks: NorbiesWorld (click on link)
