Anyone has ever used this ad network?

I had a chat with Laura Luo, Right now they are having technical difficulties with thier SDK, The whole system is off line right now and the tech support guys are working around the clock to get service back up and running, trust me they are losing money as well so they trying to restore service asap. I have already earned close to $3,000 from them and was paid every penny. Also China Holiday is coming up as well so I think payments will be delayed until May 8th or May 9th.
