Thank you one and all for your replies and suggestions. It was nieve of me to think that I could deal directly with the government and unreasonable as well since I'm sure there are good reasons to have it set up as they have it.

I am on Medicare. I purchased a CPAP online, not from a DME. How can I get reimbursed from Medicare for expenses incurred in the use of the CPAP such as masks, filters, tubing etc.

Thank you both for your replies! I checked the machine: Model REMstar 2, Domestic Model No. 1020923 Serial No. 4161807 On the front it reads: REMstar/ pro 2 (in red) c-flex The Operating System is Microsoft XP Any suggestions on where I can get the necessary software?

Where can I get EncorePro (Ver 1.4 or higher) Software and the Smartcard Reader?
