I have had the same problems for week. Very frustrating.
I have tried with different computer systems including Meridian's own ImportFour - but the problems have persisted making dBpoweramp ripping impossible.
I have informed my Meridian dealer and they confirmed that they have noticed the problems and have reported to Meridian. No responses yet.
I too emailed Technical Support at Meridian a few times in the past weeks but they have completely ignored my emails.
This is unacceptable especially given the cost of the full Meridian Sooloos systems - which I have four sets.
