When I click tab in game it says

"Fetching data from scoreio please wait" and doesn't go from there. At first I thought this is a problem with windows firewall or my LTE connection which has ISP firewall but changing to wired and disabling firewall didn't help. Also no problem with other games. Any idea what's wrong?

i have the same problem, i have try it with 2 different pc (W7 and W8) and beyond different Internet connexion : wired, wifi and different web distributor : free-box, orange-box, bbox (bouygues), ....

maybe it is normal : her leader-board data center doesn't work....

Same here...is it working for anyone else?
