I mean pictures/videos of your setup and what's going wrong. It'll be much easier to diagnose than you trying to describe the issue.
Although since you mentioned groups it might be a group issue, especially since that's an old tutorial that was made before some group stuff was fixed years ago. Shortest answer: particles need to be in overlapping groups in order to collide. So if you add a particle to group 1, for example, make sure you enable group 1 in your PhysX ground (tyFlow PhysX rollout) in order for them to collide.
