Splinter Cell Double Agent Otkhost Level?

I got Splinter Cell Double Agent. Beat the first two levels but I'm sadly stuck at the beginning of the Otkhost level,( or however you spell it). It's that level where you have to capture and take over that supertanker. I'm stuck at the part RIGHT after you jump out of the airplane, your primary chute doesn't deploy properly and the little minigame kicks in where you have to press the directional keys to get the secondary to deploy. For some reason, my chute doesn't deploy, at first I tried tapping W on the keyboard as fast as I can(that's how I did it on the demo and it worked fine). Tried the same method I used in the demo. Fell to my death. Tried pressing WASD repeatedly. Fell to my death. Tried holding down W. Fell to my death. Tried nothing. Not even going to say it again. What order do you press your directional keys, please help me I want to get this damn level out of the way. Why was I able to beat that on the demo but not the real game. Thanks for the help everyone.
