Can't find your drive - did you mean a 1693? Check and see if your firmware is up to date. In decrypter go to Tools>Drive>check for firmware update. A pop up will give you your latest version then take you to the drive at rpc1.org to see if there is a later version.
If there is a later version up date to it.
In Decrypter uncheck this option. Go to Tool>Settings>Device tab. Uncheck 'disable media change notificaton'.
Burn at have the rated speed of the media (Ritek ones your using).
You might also want to try burning the iso w/ ImgBurn. Updated burner for Decrypter - same developer.
If all those fail - what's changed pc wise since your were last able to burn?

Did you uncheck the box next to 'disable media change notification' in ImgBurn?
If you hit continue when you get this messages does it know burn the disc?
How about any changes to the pc since you were last able to burn?
