ASIO Driver not being recognized

This problem occurred though a SSL XLogic IO and XLogic X-Desk.

Playback was working as normal, then lost all sound. The meters continued to move, however I was getting no audio output through the mixer.

VST connections said my usual ASIO was missing. I believe its labeled MadiXtreme.
In the Device Setup, under VST Audio System, the drop down menu to change the ASIO driver no longer includes my MadiXtreme option.

This is very strange, never had this happen. As I said, playback was working as normal, I was working on a mix, not touching any keys and playback stopped.

Anyone else have this problem where the ASIO disappeared?

Trash prefs?

Are you Win7?

Double post.

Ah sorry,

This machine is a Mac, OS X.
