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?
