Apple Store - There was an error in the App Store. Please try again later. (13)

I just got my mini mac today, with the lion.
I cannot download anything it gives me:

There was an error in the App Store. Please try again later. (13)

And I tried to log out from the apple store and the mac and then log in, nothing helped. any suggestions ?

Do you have a valid Apple ID and are you logging in correctly when asked for the ID upon trying to download?

Yes, I also tried to call apple and they didn't know what to tell me... they told me to send an email to the support of the apple store... i DID.

I already used my Apple ID in my iPhone and a different Mac. I can't think of a reason why if doesn't let me download. I also did all the software updates for my mini mac...

If you have already contacted Apple customer service and sent an email to the App store, all you can do now is wait for them to answer. Perhaps they need to reset your ID?

Might be, anyway I will update here whenever I have a solution so other people with the same problem would have some tool for future problems.

Just a long shot but you mentioned another Mac did you authorize the mini in iTunes ?

Do you have Bootcamp installed ?
If yes unmount the drive, it might solve it

Well,,, sorry I can’t help but tell you to repair disk permission, if that won’t make it work I have to other solution

There is a simple fix to this problem. right click on the finder icon in the dock. click go to folder. and type this in the adress box "~/Library/Cookies/com.apple.appstore.plist" without the quotations. Move the com.apple.appstore.plist in the trash and empty it (you may need to enter your computer password). start the app store again and try downloading
