Forum:How do I log back in RoD

Help! I logged out of my account and on GREE and I didn't log back in. And I played RoD and made me into a new account so I thought I deleted my account. So I went to go search my REAL account and its still there. But I don't know why I made a new account while my REAL account is still there. So I went on GREE to log back in and deleted the app and installed it again. But it's still the same and I can't find the GREE logout on RoD. So please help! Thanks.
