iPod touch Authorize/Deauthorize computer count?

i've also had to reinstall windows a number of times and i was up to five but this is how you do it. you have to deauthorize all of your accounts, then reauthorize the ones you want. to deauthorize all of your accounts go to the iTunes store, click on your user name in the upper right-hand corner (it should prompt you for your password), now you'll be on your account page, in the first little box you'll see "Computer Authorizations" at the bottom of the box, next to that there is a button that says "Deauthorize All", click that, then go back and authorize the computer(s) you want by going to Store>Authorize Computer.
