I started the game through another account to troubleshoot and found that, if you follow the instructions given in the description you won't be stuck at the loading screen. Only when I tried buy additional memory slots through gem (haven't checked with rubies), that the amount of gem and rubies skyrocketed and the game became inaccessible. Don't know whether it is a bug which can be resolved. (once again, I'm emphasizing, I tried buying memory slots through gems. Don't know about buying through Rubies.)
