I don't think this has anything to do with Tons of Addons. Judging by the fact that the title contains WMP and it mentions tuning and dB, I'm guessing this is some sort of audio handler plug-in for Windows Media Player, which somehow got confused thinking RMXP is WMP. Look in your Add/Remove programs and see if you can get rid of it. This is just a guess, though; I've never heard of the program before.
