Hello,
As you will see from my thread on this forum, I have had a similar problem.
It may sound like an obvious and perhaps even silly suggestion but are you sure that you have firmly pushed the CF card into the slot?
I think that my problems may have been due to the way that I was putting the CF card into the device. I note that it needs to be quite firmly pushed into the slot and I have reached the conclusion that perhaps I was not placing it in properly.
