Anyhow best luck to the OP. Shit crashing and burning (sales stopping) is everyone's nightmare so hope they pick up.
The one good thing about CCBill is they give long term honest recurs which over time usually do well so I havnt really given up on them just havnt found any super good sites to promote.
Off porn stuff does well like Online BC and also Utherverse did GREAT when they were with CCBill then tanked when they went on their own (altho some still did ok after).
So I think as Frank said maybe it is more.. someone has got a better product and taking your sale rather than CCBill being at fault. Maybe.
