Its possible that cubase got corrupted.
Try reinstalling it from disks.
I test, but say "No key, good bye" :)
There is a small fuse on the motherboard (Falcon) check that this hasnt blown.
I test in my ST and my MegaSTe... dont work.
Failing that you can get a crack for cubase that will make it run without the dongle.
I have cracked version, but I prefer original runable version... its more stable.
Which version of cubase and what atari are you using?
3.10
