I'm not so sure about that.. try both these links, click through to the join form and look at the source of the join page..

with id in query string..

without id in query string..

Notice how the ccbill form with the id in the query string shows this on it..

ccbill_referer value='390999'

but the form without the id in the query string shows no ccbill_referer field at all.. so I am assuming that the error means they did not set the affiliate cookie and so it could not be read by the form script..

I first noticed the error 2 days ago but initially assumed it was just a fluke and thought nothing more of it until yesterday when I noticed it happening again and frequently..
