1. If i go without your aff link it loads fine
2. If i go back a 2nd time but this time with your aff link I get a 404
3. If i go back a 3rd time without your aff link I continue to get a 404
4. If I clear my cookies, I can see it again
However, if I go with my aff link (http://www.primecasino.com/?aff=52875) it works first time and every time!!

Obvious solution: stick my aff links all over your site and I’ll give you $5 CPA
