SafeDisc problem

[djordj]

This is what I've done:
1) Made IMAGE.IMG with IMAGE.CCD and IMAGE.SUB
2) Wrote the IMAGE whit Alcohol120% and SafeDisc2 options
3) Run the autorun from the CD-READER (the other slot of mine!)
4) Installed the game

Then on another PC:
1) Run the autorun from the CD-READER
2) Installed the game...ops... SafeDisc screen...ops... it doesn't work!!!

Is there some difference between my and the other PC?
What do I have to do with IMAGE.CCD and IMAGE.SUB?

Help!!!
