OK, I will contact our miner for details and post here if with his permission
running cgminer with conf
there have to be "vote" : "some number" in your config file generated by cg. only 1 "some numer" is ok, no matter how many cards you have. Any keep a blank around the colon, some of our miners got reject with this mistake
please download the trial conf

Thanks

It's working now, I just realized that my config file was missing that voting part in the first line.
Now I can run directly with CGMiner.exe.
Do let us know your miner's config if he is ready to show us, it would be really helpful.
