Wheels not spinning when doing a burnout???

[SeanBob]

hey, i'm working in 3ds max with the 4-WheelerExt and ive set up the car with the help of the Help Pages. The car doesnt seem to spin the high poly wheels or the low poly ones when performing a burnout. I've already animated part of my scene and the wheels work fine for other actions (accellerating and skidding etc.), Ive tried restarting the process and recreating the links but it doesnt seem to work :/ I also thought it might still render but that was a depserate try at the solution

If theres anything you think im doing wrong, help will be much appreciated

Regards

Sean
