Not sure if this has come up before maybe I'm doing something wrong, but for some reason I can't get the iOS version to let me log into my cloud saves; the problem I have is the "Login" button remains greyed out so I can't tap on it, even after keying in the right login and password.
Wouldn't be a big deal if I hadn't finally beaten VGT after a year of trying, only having to do it all over again!
