I have the same card and have had to power cycle the card when it, 
without identifiable reason, have lost the ability to record after 6+ 
months of no issues. I would suggest that you power off the backend and 
leave it off enough time for the card to completely reset (1 minute?); I 
believe there is a firmware loaded at some point which we want to ensure 
is reloaded completely.
