Underworld WMVHD ERROR playing it

I just recieved my copy of Underworld WMV HD, I put it in the DVD drive, and it loads up, the menu comes up but when i try and play the movie, I just get an error message...

Does anyone know what is wrong, and how I can fix it, I have a fresh install of windows media center 2005..and I am using a Pioneer 109XLS DVD drive, before the film launched i got several alerts from microsoft antispyware, telling me than an unknow application has installed it self, but i set it too allow it to run, so i don't think anything is blocked, like the license generator...it coes me £25 and took 9 days to arrive and now I cannot play it, I know some popele on here have WMVHD,'s and was wondering if they new what was wrong..
