Half a year has lapsed since Nora's post and the PROBLEM still exists! Express Scribe Pro cuts off the audio on some DS2 file types (I have validated the DS2 file was good, not corrupted). I have been using ES fine, no problems, until I got a customer who wanted me to transcribe a DS2 file. NCH's web site misrepresents that Pro version is compatible with DS2 files so I downloaded the trial version. Kept cutting off the audio, attorneys kept trying to resend the file -- no luck. Spent more than 10 hours trying to download "converters' and work-around fixes which did not work (but did mess up my computer big time). Exhausted, exasperated, I had to tell the client I could not complete the assignment (and I probably lost the customer forever).
To add more insult, uninstalling the defective Pro software to go back to the basic, free version and whola -- no I have completely lost the use of my foot pedal. NCH is now holding me hostage - pay for the defective Pro version or basically lose the ability to transcribe (normally) with a foot pedal. A terrible disappointment. I will not be recommending and referring associates to NCH any longer. I used to rave about them. Terribly, utterly disappointed. It's hard enough to make a living doing transcription work in today's economy and having to add in all this aggravation makes it a living nightmare!
