Can't update apps nor purchase new apps
Hi everyone, could someone help me? I've had my iPad now since last year August (2010). But just here recently, actually, yesterday, I changed my password for my Apple ID. Since than, I have not been able to make updates to the many apps I have on my iPad. I now can't even purchase a new app. I don't use a credit card to purchase, I use the iTunes gift cards. My address is the same and yet, just since changing the password, I can't update. Does anyone have any suggestions or solutions. thank you.
