iTunes problem

When i reformatted my PC and reinstalled iTunes i plugged in my iPod touch and it backed itself up and placed the movies/tv shows back onto my PC and about 5 of my Apps.

The other 30 or so apps were not backed up onto my PC because it says they are not authrozied to play on this PC. By the way i DID authorize my PC with my iTunes account. All of my other purchases work fine except these.

I don't have my Apps backed up otherwise i wouldn't worry but the ones i have left are worth over $50 and i can't afford to repay for them.

How can i get them back or authrorize them to play?

 

Try installing Quicktime. iTunes and QuickTime rely on one another to function properly even though you don't have to have them running at the same time.

Be sure to restart the computer after installing QuickTime.
