Problem with Daemon Tools and SR7.Stop

[Keyser_Soze]

I have a problem, I installed Daemon Tools 4.0.3HE (latest), and SR7.Stop 1.2 (also latest), but I constantly get error messages... If I use just Daemon Tools, I get "A required security module can not be activated. This program cn not be executed", and when I start SR7.Stop, I get "Nothing to hide"... what can be the problem? Btw, the game is Total overdose, if it means something

How did you create your image. Do you have enabled a drive in Daemon-Tools? Do you really have the latest version of SR7Stop? Did you mount the image?
You can try CureROM or Pr0tSt0p, the follow-up of SR7Stop:
