ummm... that would be because
1- the mod you link to is for 1.1.x only.
here is one for 2.0.x http://custom.simplemachines.org/mods/index.php?mod=1804
However it doesn't do what you want anyway...
It ASSIGNS new users to a default membergroup - it does not allow them to PICK a membergroup.
So, it would appear that no one has made such a mod for 2.0.x
