From your description I am not entirely sure what the issue is I'm afraid. You need to send the coins to the btc address shoeing when you click on where it says "account" at the top of the screen. I'm not sure why you keep on getting asked to change your pass phrase and PIN, normally you are only asked to change your pin when you make a deposit for the first time, unless that's now changed and you are prompted to change your pass phrase too?? Can anyone else offer any insights here?
