It downloaded fine for me- I opened it- up comes the Daedalic logo and then it bumps me back to my startup screen. This happen to anyone else?

I don't know how many people have actually tried the demo.

Could the problem be due to your video card? Or maybe a conflict with another program that's running in the background on your computer, like an antivirus or software firewall?

Challis3, I just downloaded the demo and just started it: it worked fine for the small amount of time I played it. I'm using Win7.

Using XP and tried the demo yesterday, it worked fine for me. Though I only played a few minutes - didn't like it.

I played and finished the demo. I had no problems with it either. I use XP home.
