"SECURITY MODULE" error, what is it?

[BarryB]

Add Starforce Nightmare 1.12 to the list. If it's still open when you run a Securom 7 game you will get this message:

A required security module can not be activated. This program can not be executed.

So if you use SFN to disable your CD/DVD drives make, sure you exit it before running your game.
