OT: Judge Dredd

[venommous]

Hi, all,
I have JUST joined and in desperation am asking a question about the Dredd vs Death game: I have only just started the game but cannot get the door to open at the end of the "agility" section - where Dredd has to go over and under objects. Despite finishing this room any number of ways, the door will not open at the end and consequently I cannot even START Tthe game.
Is this a problem with my game or PC, please?
I have downloaded the latest official patch and this has had no effect. Is there even a cheat code so I can walk THROUGH the door in order to play the game further?

Please help, someone.
Regards,
V

PS I hope I've posted this in the right section!
