I was on an Ipad2 when my game was locked out. I started a new account on an Ipad mini, which worked just fine. I had my account transferred from my Ipad2 to my Ipad mini. Once my account got to the Ipad mini, I was still locked out. My Ipad2, however, could download and run a new modern war account.
I have an Ipad mini2 that I have asked Gree to transfer my account to on December 2 (Ticket #2091288). I am interested in seeing if a more powerful Ipad can download my account an allow me to start playing again. Once it is transferred, I will let the forums know if it worked.
