iTunes won't work

[Magus]

Have you tried reinstalling it once first to see if that fixes the problem?

yeah, i reinstalled it about 4 times already. The problem persists.

If iTunes fails to load, there may be another related program that has "stopped responding" and is in turn causing iTunes to wait. Restart your computer, and try loading iTunes again. If it stops loading, press CTRL+ALT+DEL (or CTRL+SHIFT+ESC) and look at the "applications" tab. If any task listed there says "not responding", try ending that task and seeing if iTunes will continue loading.

That is what i did, but there is no changes in the Applications, iTunes doesn't even appear there, but does in the Processes everytime i click on iTunes it appears in the processes for a second about the moment that loading sand thing your cursor turns into when the computer's working and then just disuppears again.

Edit: This is my exact problem http://discussions.info.apple.com/we...a4.7@.68ae97bd
but i barely have anything that could be a problem to iTunes and i tried to disable everything at Startup already, still not working.
