I have been answered by Starforce support department because I sent them a email with my problem.
I want to thanks them to answer so quickly. So, thank you :thumbup: .
The told me this:
Hello,
Try to do the following:
1) Right-click on the game's shortcut, select properties and click "Run as administrator";
2) Run the game;
3) It will ask to reboot the PC;
4) Don't reboot;
5) Run "sfdrvup.exe" from here: http://www.star-force.com/protection/users/ ;
6) Reboot.
I haven't tried it yet, but it surely will repair the problem :smilewink: .
