Mike Wilson's Ant's on a Mobius Strip animation, Help

[gohj]

Mike Wilson web site has example animation of chain of ants moving over surface of a mobius strip.
Leader ant has 6 mates; Follower ants have 7 mates each.
The example animation ("animation none")shows 100+ movement waypoints in a 10 second time span.

Problem:
I want to do a new animation, one where I move the ants with fewer waypoints than the example.
Problem is I can't get any of the ants to move! I select "Ant 1" and try moving it, but nothing happens.
None of the ants are Fixed; none of the mates should be locking the ants in one fixed position.

What am I doing wrong? Has anyone else downloaded this example and been able to move the ants to create a new animation.

Nevermind.
After re-extracting the example animation file I found I was able to move the ants, so lock up must have been due to something I had done.

The trick to doing this type of animation it seems is to have an enormous amount of movement waypoints.

The ant animation works if you move the ants around the circuit with 100+ waypoints, but when you try a lesser number, eg 8 waypoints, the animation will crap out because the mates get confused.
