Oh dear. StarForce got dropped by many commercial game developers as a cd-based copy protection system due to the havoc it caused with some end-users' registries. Also, the process you need to go through after installing your game is a tedious process. It installs drivers for the StarForce engine, forces you to restart your computer, then you have to put in a serial key which is checked against hidden data in the cd's descriptor area.
I have several older games that use this copy protection scheme, like Prince of Persia Two Thrones and Sudeki, and these days Sudeki just refuses to start, insisting I do not have the correct disk inserted.
Hehehe. Sorry. I may be a bit biased, but StarForce is a real headache. However, if it is what you need to solve your problem, by all means, use what works for you.
