About a month ago, I bought the next campaign level: "Dark Forest Campaign". I recently had to switch iTunes accounts, and now I would like to buy the next 3 campaigns. Problem is, when I click on buy, it brings a message saying "You must purchase the app that this item is for before you can purchase the item." What I think this is saying is that I previously bought a campaign, but not on that iTunes account. Is there a way to fix that? I can't even "re-buy" the other campaign I previously bought.

I have tried re installing the app and re starting the app. Nothing is working and I think it's because of the account issue. Please let me know if this has happened before!
