The issue is with all the files or just with this file because could be the file also the problem? Try to reinstall. Uninstall your software first, then go to the folder location below on your computer then delete the Express Scribe folders:
C:\ProgramData\NCH Software
C:\Users\(Your computer profile)\AppData\Roaming\NCH Software\Express Scribe
If you can't find the AppData folder, set Windows to show hidden files and folders with the steps from this link: https://support.microsoft.com/en-us/help/14201/windows-show-hidden-files.
After deleting the Express Scribe folder, restart your computer then install it again.
