Thanks, that's really peculiar. It's asking for the number of devices and seemingly responding that asking for the number of devices is invalid.
This is going to be tedious.
OK this test version doesn't ask for the device count (eventually Deathray will support multiple cards
), it assumes there's 1 device:

Fingers-crossed.
