I can testify to personally having had a StarForce issue. After I installed CodeName: Panzers 1 & 2, I played them a little bit. Then I got the update patch for #2. The installation went well and it asked me to reboot my PC. I clicked yes. My computer proceeded then to start to boot, but never got past the very first boot cycle (where it shows you your devices). I tried everything I could think of to restart and it still would not boot. The only reason I am still using my PC today is that my dad found something about it screwing up USB devices, so when I unplugged them all then my PC booted. Needless to say I am not going to play another SF game again (learned my lesson). However for a couple of hours I thought my PC was going to be a vegetable for the duration of its existence.
