I did not see a .limewire preferences folder, but I did try and download one of those MagnetMix files. I was getting 615 Kb/s to 685 Kb/s while downloading from them, does that mean that people I've been previously downloading from just have slower connections than what they have listed? If so that would explain the slow download speeds.

I will try downloading from several users to see if I get different results, if users have been lying about their connection speeds I'l be able to find out by trying different files from different users.
