Hi, Does anyone know how to troubleshoot or fix this problem? I cannot install the new update on my sprint htc phone, I keep getting and "unknown error code" Also I cannot sign in with my regular email password as my email is not getting recognized here? ( I signed on as a guest) I can get on the game site on my phone but it wont let me play and keeps telling me to install the new upgrades, even though I did it once already, and after numerous re tries it still wont work.
