 Have you gone into your deck configuration settings and attempted to add a channel, or if one was already there, did you try deleting it and adding a new channel?

 YES i  try evry thing .

mrg:

 YES i  try evry thing

No, i bet you didn't.

Did you try another programm to see wether the problem is related to your hardware or your software? Did you confirm your deck and cables are fine at another system?
