I didn't quite understand how the cpap supplier could download it if the doctor's office was not able to, but I did as I was directed. It turns out that the SD card was corrupt and the DME gave me a new one. They were able to download from the machine (as just for the heck of it, I had packed up my machine and took it with me to the DME location). The information from my machine was faxed to the sleep doctor's office and hopefully within the next few days he will be able to view it.
Do all of you take your machine with you when you have your 'check up' appointment with the sleep doctor? Is this something I should be doing in the future? I have no idea how the SD card became corrupt, didn't even know that was a possibility.
