Thanks so as your support ticket staff told me i tested the solution he sends me round about 4 times in every possible enviroment ( save mode, no other side progs, without antivirus) and this solution does not work.
Hello,
please try to completely disable/uninstall your antivirus and/or firewall and
do the following:
1. Exit Steam.
2. Right-click on Steam icon.
3. Left-click on "Run As Administrator".
4. Right-click on the game in Steam Library.
5. Click on "Properties".
6. Select "Local files" tab and click on "Verify integrity of game cache files"
button.
7. Please wait, the process can take several minutes.
8. If the issue persists, reboot your PC and try one more time from step 2.
