Affiliate Plugin Setup/Tracking

I CAN NOT get the affiliate plug in to work!

1. Multisite install

2.Tried Network activated & single site activated

3. Will not track clicks or new blog/site registrations.

4. Paid Membership Pro as site/blog registration.(one paid level – no free level)

What did I (do/not do) or need to do to make this work and track new blog/site sign ups?
