mike do not uninstall, the problem i'm 100% sure is that you are entering the wrong information and that's why you can't recover your password
so uninstalling if you don't know your email, will mean you are stuck out
the solution, do you have an android? if so, you are in luck
i'm uploading an update right now, get it when it is out, on the multiplayer next to your name you will see a new 'edit' button, you can change your name in there
