Oh my god... I downloaded infinity blade 2 when it first came out, and I decided redownload it after the update. Then as I press install, it says that there has been a big update and I have to purchase it again. What is this? I can't believe Apple has done this. Either it's them, or it's hackers because it's telling me I need to change my security info...
I really doubt it's hackers... I think when itunes says you need to purchase it again they mean for you to just redownload it for free. I updated infinity blade 2 without any problem.
It says are you sure you want to purchase infinity blade II. It used to say install, now it says buy. Aw well, might as well rebuy it I guess.
If you see the app price instead of "install" in the AppStore, then you are probably not logged in to iTunes, or not logged in to the same account you originally purchased it with.
Sounds more like you're using a different account. To verify that you have purchased IBII on that account, go on iTunes on your computer and check out your purchases history.
I did what you said and went thought he download history on iTunes... That's weird that it used to say install, then it popped up saying that there was a major update so I had to re buy it. It didn't even pop up on download history on my iPad though.
