Hello .. from about 2 days I tried to download the new update but an error has happened and damaged the game so it said that it will download 800 MB and I tried to do that but an error has happened then it said that I have an old version and I have to download the new version and I did! but after I did that and installed the game I tried to open it, but it gets the "Loading ... please wait" screen for 1 minute but the log in box doesn't come up then it automatically close!
I tried Completely UN-Installing the game then installing it again but nothing HAPPENS !

Please help me! I want to play the game again
