So you are trying to withdraw your winning which I assume came from the free chips on the registration? Correct me if I'm wrong, but I doubt that anyone is willing to deposit into this new site. Just for your information, there was a site which uses the same script and the site required a deposit once the player want to withdraw winning from the free chip although they removed the rule eventually. Not so sure if this site has the same rule as the site I'm referring to. Anyway, I think you do not need to hope too much from your withdrawal. There is no signs that this site is paying, like the other sites uses the same script which claims that they pay many players but they cant prove it.
So far I haven't seen any sites using this script with good reputation. Most of them came to this forum by creating an ANN thread, offering free coins on sign up then the representative gone ignoring the topic. Lets just forget this site, move on to other more reputable sites. Dont be attracted with new sites using the same script anymore in the future as it can be the same as the other previous sites.
