Yeah, making sure your computer meets the requirements is one thing. But seriously, mine is waaay above the requirements, and the trial version won't launch, asking me to DOWNGRADE to directx9 from directX10.

Now, how do they expect to sell any games that way? I'm pretty sure I'm not buying it... :-(

how do i get the better version of the trial there a place where u download the trial with more parts

It's sad really. An up-to-date Vista computer will have directx10, not 9. So basically, they are releasing a demo that doesn't run on Vista.

you can have 2+ versions of direct x installed at the same time.
vista comes with DX10 and also with DX9d
