From the aff site:
Dear First Gaming Partner Affiliate,
Unfortunately the Rival gaming platform hasn’t lived up to our expectations over the past few months.
Because of continued and prolonged processing problems you might have seen your conversion ratios
and player values erode. We had no other option, but to drop Rival. We sincerely hope that Rival will
continue honoring their affiliate commitments as they have done in the past. Your players will be able
to continue playing on the sytem and thus you will continue receiving checks from them. However
we ask you not to send further traffic to our front page.We wish you continued success in your affiliate endeavors.
Best regards,
First Gaming Partners Team
