So I've been wanting to buy some in app purchases on an app (specifically uberstrike ). So to you fellow uberstrikers out there. My friend gave me a $25 iTunes gift card and I decided to use it on this app. I went to the UBerstrike game, went to the shop, and click on buy credits. So I wanted to buy 2 packs of 6,900 credits which is $10 a pack. So I click buy, then a prompt comes up from the Mac App Store Saying """ Confirm Your In - App Purchase Do you want to buy one 6,900 Credits for $9.99? Cancel Buy """ I click buy Another prompt comes up from app store and its just simply entering your apple ID and password. So I do that then I get this """ Security Info Required To help ensure the security of your Apple ID, you must confirm your password and answer your security questions. """ Then I have to enter my Apple ID and pass and I click continue. Now here's the problem, when I click continue it opens the Mac App Store. Its just on a blank screen and doesn't show anything :/. So some help here? Uberstrike > Shop > Buy Credits > Confirm > Enter Apple ID > Security Question prompt > Opens Mac App Store > Won't Load?
