Well, i just installed the iTunes 10.6.3 update and have had a very big problem with it and don't know why. I open it up and i get an error saying "A required iTunes component is not installed. Please repair or reinstall iTunes. (-42404)" Does anyone else have this problem? Because i have noticed that i can not purchase anything on the iTunes store and it also cannot find my iPod when i plug it into the computer. Everything else is still fine, i can play movie and such. Just can't do those things. Anybody know how to fix this? I have tried to reinstall iTunes and it does not work. Any suggestions for some +rep?
