**** im good. k fixed it for realzies. no using crappy backdoor products. heres a step by step fix.
first back up your library and you playlists if you do not know how to do this. make a playlist with all of your music in it. then right click that playlist, click export. export it into .XLM format.
2. go to your control panle and get rid of itunes. (complete uninstall)
*edit* cause im dumb...delete your itunes folder from your music library. should be right in your music subfolder if your using windows 7 or vista.
3. go here and download the 10.3.1 ver. http://support.apple.com/kb/DL1103 (don't worry its actually on itunes)
4. install said program (it may ask to install newest ver. you know the answer to that lolol)
5. import your XLM playlist. if you dunno how to do this i shall show u now. go to the top of your screen where it says file. then go to the sub folder library, and then there will be another sub folder called import playlist.
now don't go downloading itunes 4 again. its crap. no difference anyways...
*side note*
there all your playlists are back and your key board works again. if your like me and have like 20 gigs in music the importing of playlists may take some time lolol.
