There was an error in the App Store. Please try again later. (undefined)

Have this exact same problem in the UK. And my purchase history has gone, might want to check yours too.

Tried everything, from having my credit cards checked to setup another account...
and finally sent Apple an e-mail asking for help.

I seem to be having this problem as well in Canada and most of my purchase history is gone as well. I haven't come up with a solution yet, have tried quitting application several times and rebooting computer several times and its still not working. Can't contact apple or at least don't know how, most frustrating as I want to install an app but can't. ARGH!

I've got the same problem. Tried so far to purchase apps and to update one of my already installed app. Both didn't work and the error message is the same: "Your request is temporarily unable to be processed. Please try again later."

It looks like my problem is still a little deeper, in the iTunes account. In one specific account, I don't get my billing info verified after I try to update or purchase a new "free" app. As well as I cannot reset the account notifications...
In another test purpose account everything works like clockwork...
It's my ****** account which has been appleducted...
But yes, you are right about some broken links in the app stores... have noticed that myself, but there's always a way around them.
Tks from China...

From what you described it looks like corrupted database affecting some accounts only

Perhaps at Akamai.net or Apple?

one can just hope no purchase history was lost (or compromised) in the process

Same issue here. I have tried all suggested solutions with no success. The difference is that I am NOT able to buy whatever link I click. (sorry about my poor english)

I am having the same problems. I tried different links in the MAS, signing out and in, restarting etc. Nothing solved the problem. I still always get:

'Im App Store ist ein Fehler aufgetreten. Bitte versuchen Sie es zu einem späteren Zeitpunkt erneut. (undefined)'

Any further hints?

Well, so far I have tried everything suggested, including the update, checking billing details, restarting, logging in and out, and I'm still stuck.

Further to my last, apparently I can download some new apps, like the free firelight one that's at the top of the popular list, but not others!

I'm having same problem. I downloaded free and paid for apps yesterday. Today only free apps download. Otherwise, I get the same error message.

Just did that and guess what??? I get the same message if I try to reset the notifications or if I try to update any banking info...
It's not my day, I guess...

I am trying to purchase a game and getting the same message. Have rebooted, tried all the steps posted but no luck. App store really works well!! Kudos Apple!

i tried this aswell and it worked perfectly! very weird
