Win 7 Unresponsive mouse and keyboard

[ZONTERQ]

When I go into battle the game does not respond to the mouse and keyboard

But the game is running (time is running and the battle is going on).
But I can not even choose a squad and equipment, the mouse just does not respond to anything, not one key does not work except ALT+F4
I've never had this before, everything was fine before, I've already reinstalled the game and it didn't help.
