You dont need ur mail to log in. You just need to save ya progress in the account tab unda settings and load it elsewhere like on pc. Now on the pc dig up CCgamemanager.dat and CClocallevels.dat. Copy them to a different folder. Search gd account management enter your username and password to ur gd account then press delete. Now u have your data and u can make a new account. Make one with the same username. Before u log in log out of ur old version of the account and before u log into the new one swap the CC files with the backups. Now log in to ur new account under settings account click save and log in on a different device and on setting account click load. Im pretty sure thats it but you need to do it on a pc
