Garageband 10 in-app purchase. App Store shows blank page.

neither this nor the official solution with the accept button worked for me

Solution didn't work for me either. App Store asks me to answer my security questions after clicking 'buy' in Garageband, and after entering my password it just shows a blank page.

I had the same problem.

Found out this happens when buying the extra content is the first purchase you do after installing Mavericks.

When you go to the app store, buy any app, and then go back to garageband and try again, it will work.

It did for me.

(bought an app I wanted anyway)

In my search for a solution I found another post that said it also works when you buy a song in iTunes, but I'm not sure about that.

Thank you, that did the trick for me!

Graag gedaan ;)

Thanks FrnkN

Your post is still valuable as it was the only answer I could find after hours of searching that worked.

Thank you so much FrnkN ! By purchasing another app, I had to enter the answers for the security questions. After that it was able to download the extra content in Garageband.
