thank your very much, Shawn!
i got only one question left: is it ok to use it right now? because i followed the steps of this tutorial (this thread) before i asked for help. i didn't restart or log off yet. should i redo those reg edits before i run the .reg file you just attached? i could just do it (just redo tutorial edits first), but i'm curious about the effects it may have. your file must change completely other keys, right? but for not, there will be potentially harmful incompatibility, right? please tell me, for full clearance.
UPDATE: well, i just redid edits i made by this tutorial, then run the Restore_Libraries.reg and got the same message as before
