Can't get IK to work in demo version

I downloaded the demo version of Animate and follow all the tutorials to figure out how the software works and whether this is something for me.
All looks great, but I just can’t get IK to work with a characters feet nailed to the ground. It just keeps turning around it’s body pivot point and the feet go everywhere.
This is so with my own character but also with any demo character from the tutorials I load. It looks so easy in the online movies, but I have spend hours trying to get it done and it doesn’t work.
Maybe this is a bug in the demo-version?

Hmmm, I figured it out already. You have to ‘Enable Translation If Top Of The Hierarchy’ on the main body part to get it working. Why doesn’t it say so in the tutorials?
I just pushed all the buttons and combinations to try everything out.
