I had Windows Vista on a Gateway laptop on which I used Express Scribe Pro v 5.63 whenever on vacation to download and transcribe medical dictations. I had no problem until I purchased a Dell laptop with Windows 10. Now, when audio files are downloaded to Scribe, some of the files are incomplete, showing roughly 20 seconds of duration when they should be 1-3 minutes long. The slider moves across the bottom of the Scribe window, but I have no audio. This issue affects only about 3 out of 10 audio files each time. I have been in contact with the NCH support team who says that Express Scribe Pro is compatible with Windows 10, but they cannot resolve this issue. I am desperate to find a solution, as I would like to upgrade my desktop from Windows 8.1 to Windows 10 with the free offer, which is good only until July. I am running out of time, and since my desktop is used solely for my work, I cannot upgrade until I know for sure that Express Scribe will work. Please help me. Thank you.
