Fifa Club Manager

So, when I click go, game counts days, but at the end (when it should load inbox screen etc.) it stucks for a long time, like it's loading infinitely (and when I click "cancel" button, it doesn't do anything). Sometimes it loads after 20+ minutes, and sometimes it doesn't. What's the prob?

you only need to wait till the game pass the day, even if it's more than 20 minutes.
No other solution, the game is working, working, working...
