Was it one of the devices pictured
here? There is an older driver on that M-Audio drivers page, and a newer one on the Avid site linked from
www.avid.com/drivers on this page:
Fast Track USB Drivers
You are correct that there is nothing registered in your Avid account, so there would be no downloads there. You probably had Pro Tools Essential or Pro Tools SE software included with the hardware, and there were no full downloads of those ever posted.
You have a previous post on this forum from May 2011, so I'm guessing whatever hardware software bundle you got at Christmas would have been a product from 2010.
I would start by trying to get a driver version installed that will work with your device and your current operating system, and then try the device with something like Audacity which is free and works with ASIO devices.
