Inverse dynamics tutorial

Hello i am a student, and i have problem with tutorial about inverse dynamics. I was doing lesson number 3, but UpperBoundOnOff in crierion didn’t worked, in model tree te value was set to “On” but still activation of some muscles was above 1. I was doing everything according to tuttorial and my version of AnyBody is 6.0.4.16344.
And could someone tell me how to insert AnyMechStudy class, I was going thru modle stree but after clicking Insert Class Template program was freezing and i couldn’t do anything.

AnyBody will break the upper bound if there is no other way to carry the external load. This might be what you are seeing. The alternative would be that the system would come back and say that the problem is unsolvable.
