Hi Jimmie
We have a SD2 at our venue that we bought two months ago, and I to had the same problem.
We are fortunate that We are right here in Los Angeles, just as ADJ/ Elation.
A couple things I learned is that you will need a maximum of a 64m CF cf card. I had tried a 4G, and even a 1G card and the SD2 would not see them. I know kinda whack, but?
If you can not find one localy, Elation does have them in stock.
The other thing is kinda weird, but tech support had me load the cf card before I turned the SD2 on.
Well it is kinda weird, but that did work.
Hope this all helps you?
