Describe more you problem so someone can help, what is not working exactly ? Make some screens, post it in here or send to game support.
Did you try download direct from RedFox site ? Someone had an issue like this too : http://forums.playredfox.com/index.php?threads/two-issues-after-this-maintenance.50706/ Solution for him that worked : Other I always suggest : Try add again the exception of the path to your antivirus. Try again use the compatibility mode in Windows and run as administrator. If you have a virtual machine running on your PC uninstall. Try update all your drivers.
i sent so many tickets about bugs crashes and even in game change`s, GM reply its my pc (the same pc i am using since idk) so i will tell you the same answer your pc and network connection is the reason we "RedFox" don`t have tactical support because we have the power of ignorance and our staff is fresh graduated losers. so please change your pc and your network connections, if the problem still appear just uninstall the game and find something else.
