How do I get rid of it?, No matter what, it won't release me!

Ok... so I thought I'd try it out, didn't find it pleasing, and tried to uninstall SXBandmaster. I thought I was through. But it would not let me go! I can't find any reference to it anywhere in my computer or registry, but still if I want to freakin' download anything in Firefox, it reverts to the nonexistent SXBandmaster. I can't download anything. This has been going on for somewhere around half a year now, and I'm sick of it. I don't want to reformat my drive and reinstall Windows just because of this one program! Everything else is smooth, and I have too much set up to just start from scratch. Please, if anyone can just help me remove SXBandmaster ENTIRELY from my system, I really, really appreciate it. I've tried reinstalling and then uninstalling again a couple times, looked through my registry, and have done a search for anything to do with it, but I don't really know what I'm looking for, so I can't make it go away.

Thanks in advance for any help...

Close Firefox when you uninstall SXBandMaster. If this doesn't work, just delete sxbm.dll from Plugins folder of Firefox.
