I didn't try the installation disk suggestion because I'm away at college right now and have the disk at home unfortunately. I did create another user account and tried that.

I wasn't sure how to find the file when under that name, so I put it in my shared folder when I was under my main account name, brought it up under the Test account, and deleted it.
I then started Limewire and I noticed that it did something different than what it does on my main account when I open it for the first time since reinstalling it. I've uninstalled and reinstalled Limewire numerous times, yet never (except the VERY first time I ever put it on here) did I get the screen that pops up where you click next, next, etc and choose your LW preferences and what you want shared, etc.
I did get this screen when I opened Limewire on the Test account, and the file was not downloading! I got excited, thinking it was gone, and switched over to my Main account, opened Limewire only to find the pest still in the downloads box trying to download....

(PS- thanks so much for your help... i really appreciate it)
