This will happen if you are using bad proxies IPs. Proxy IP addresses must be active and "good proxies", otherwise your plays sent by the program never reach to intended site to deliver the plays. Either use verified active proxies or no proxies and your plays will then be delivered properly. You can check for proxy list for free here:  http://www.checker.freeproxy.ru/checker/
