I have exactly the same problem - this piece of equipment comes with the most unhelpful documents personally I don't think that it is fit for purpose. At a time of plug and play this clearly doesn't qualify.
My first recording was left in over night as it said it was finishing- and then needed to go through task Manager to come out of the loop only to find that the recording was actually completed and in the folder.
Latest attempt came up with image and sound press play and image disappears and sound remain. Try again and all it says is searching.
