"protection System"...

Every time I try to run ER:T it gives me this protection system, and almost half the time, I will have the correct disk in, then It will take its precous 2 minutes reading the disc, and It will say I don't have a liscened disc in, then I have to restart my pc before it starts correctly reading it again. Is there any way to get rid of it or stop it from being stupid?

get the newest starforce driver from their website and/or download the starforce fix from our download section and see if any of those helps you.
