ITunes account disabled, repeatedly by Apple

Question

every week i have to reset my iTunes account...any ideas?
i won't keep a credit card on file for security reasons, could this be the culprit?

Answer 1

Here is what fixed it for us:
After troubleshooting the issue we determined that my wife's MobileMe account was being disabled every time she tried to buy something from iTunes, or update her apps on her iPhone. So her account may have been legitimately disabled the first time by hacking attempt or someone using the wrong ID, but every time after that was because we didn't know to do the following in iTunes. First, re-enable the account and set a new password (this is the most frustrating part, because over the last month we have churned through a LOT of passwords). Then from iTunes go to Store\Sign Out. If you have an iPhone go to Settings\Store\Sign Out. Now sign back into both places with your new password. After doing this her account no longer locks when she tries to buy something from iTunes or update her apps on her phone. For some reason the "10 attempts before disable" rule does not apply with iTunes even though it is the same account as MobileMe. iTunes would disable the account immediately upon trying to make a purchase. It would be nice if iTunes gave you a chance to type the new password when it found a mismatch rather than disable the account immediately.
For the record; many e-mails, IMs, and a call to Apple support were completely useless, every time the account was disabled we were told that was because someone tried an incorrect password 10 times. Thanks to everyone who posts their findings out here, we wouldn't have figured this out without your help. I hope what worked for us will work for you.
