You mean something like HotScripts.com (or the many alternatives): http://www.hotscripts.com/listing/adquick-2-11-adbrite-clone-php-script/ In regarding to Paypal disputes, if it doesn't go in your favor, you can always dispute it with the bank (worked well a couple of times for me).
I think this scripts is fake script, they didnt work as well as ppc engine, some klik can't work and delivery money to publisher and can't be reduced at advertiser. This is terrible, phplemon try to make nice frontpage, but in another page, this is just fake script. Just like in his demo, he didnt provide frontpage and backend demo connected, he talk to me that was security reason. But i think he tried to hide the truth, just fake script....stay away from it.
for a few days after my previous posts , phplemon conctact me and he support me as well as he should, and until now he still supporting me. I think this was a mistake, I just cannot wait and I get hurry to be an angry. Once for all, i am sorry to phplemon about my previous post . This script is reliable, and all feature is work as it should PPC Engine, some still need to be fixed. If you need powerfull script ,cheapest one , and ready to be a patient , i recommend this one.
Still there are people here who didn't get their money back or their sites working as they should (and as they are advertised to work).
I also had the same story as yours and guess what ? I also opened a PP dispute and got my money back.
