Dear players, Next Tuesday, 15.09.2015, our security system will receive an update that requires Security Update for Windows (KB3033929) installed to run the game. Due to that fact we recommend updating your operating system for all Windows 7 x64 users in order to be able to launch the game after the maintenance on September, 15th. Windows Vista x64 users will not be able to launch the game after 15.09.2015 due to the fact that corresponding security update was not issued by Microsoft for that OS. UPD: only x64 systems will be affected. Please read the guide to find out how to install the corresponding Windows Security Update.
