For security the software i was launching uses the registration details to unlock it.
Clickbank do the test purchases but use random strings of characters for password and email addresses, so don't get the registration email and then can't unlock the software.
Idiots... so at the morning of the launch they still haven't approved the product.. (even today 5 days later they haven't, now they want to see the download page which they saw last week and downloaded the software from..idiots!)
So anyway in a bit of a panic I added my product to digiresults but couldn't get it to integrate with Wishlist member. So I called Andy the owner on skype and asked for help a few minutes later I am talking to his chief programmer who comes up with a solution in minutes.
Since then everything has worked perfect. Customers get registered flawlessly, Affiliates get paid instantly, and i get stats that are easily readable.
The only slight issue with DR is that their documentation is almost impossible to find!! But the help desk is very responsive.
I am actually going to look at adding a DR option to all my products.
Highly recommended and I hope they get the success they deserve.
