Affiliate Plugin - still cant get it to work

Still trying to get this plugin to work.

I've tested clicks from various computers, cleared cache etc but not tracking any clicks yet.

I have been having some other issues with my site, but not sure if this is related.

Also using the multi-db plugin and might be missing tables?

If this is answered elsewhere apologies, I've searched a number of times.

Slowly learning about the db's, so if its a table that I'm missing, which one should I be adding where?
