Europe has stopped running. Friends HELP ! (Europa Universalis 4)

The incentive of playing in Europe for a long time, but recently it ceased to run, for a couple of seconds shows that I launched, but the launcher does not start. Tried everything : reinstalled, deleted the crack, but NO ! No pirates, nothing more is downloaded, please help !! And Yes, I have Windows 8.1, but good game, and now will not start. It was recently - once started, all the rules, but the next day again the same Signa.
