Affiliate and Membership Problems

Hey guys, im back. I was just on a support chat and they told me to come back to you. I was able to get the affilliate plugin to work after our back and forth, however upon testing I found that if someone clicked on an affilliates linked banner and signed up for a FREE account it was recorded as someone signing up for a paid account. This obviously will not work seeing as we do not want to be paying affilliates if people are signing up for FREE accounts through their link...

The guy on the chat suggested I mention something about an RC for the new membership update...

please advise
