I downloaded the model but can load it because I don’t have:
…\BRep\ Aalborg\ToolBox\ Markersets\ KitVaughanMarker sR.any
Can you zip it all together?

No worries. I looked at the model and your problem is that the model
is over-constrained. If you have a look in the JointsAndDrivers. any
you will see that you have constrained the hip with a AnyStdJoint and
you also tries to drive it with a marker.
The same kind of joint is used at the foot which you also tries to
drive with a marker. At the same time you tries to drive the knee and
the ankle in the x-direction. If you outcomment the AnyEqSimpleDrivers
your model will run because this removes the 4 constraints that makes
the system over-constrained. I don’t think that is what you want… is
it? I think you wanna drive the foot, ankle, knee and pelvis with the
marker data?
You only have one marker for the pelvis?
Let me know if I am right and I will try to guide you through:D
