According to the latest information on BestEthanol (bestethanol.com), the program is having problems with accessibility to their AP account. Probably it was blocked or something as their AP support was "offline" during weekends. The administration of BestEthanol is trying to solve the problem.
Currently admin keep paying regularly to others PPs. As to Mario, the admin of BestEthanol, in case AP doesn't answer, he will pay AP pending payments using other PPs. It is nice to see the admin is fighting for his program. Good luck!
