If you really need the disc, I'd try contacting Gommert at Butel and see if he will sell you one for a few bucks.
I think the software on the disc contains the same as you can download though and maybe some copies of other models time limited demo software as they would all need paid registration keys to work. The download version would also be current while the cd copies could be out of date.
I don't know what to think about the parrot though.
