Upgraded from 2.03.02 to
2.04.03 FW today and looks like it is
back working again! I can also see my recordings from past days (so it was recording fine, just couldn't access). As far as the microphone goes, not sure, will have to check back a few times to see if it saves my prefs on that, plus also see if the whole thing continues to work after shutting down at end of day and restarting in the morning.
