Hi Reino and all,

Note: My computer knowledge (15 years ago) was Intermediate at best.
Prior to sending out my first email, I checked user>AppData>Local>WSJT-X for All.txt, WSJT-X.ini, wsjtx.log files (I couldn't figure out a way to attach the .jpg file to show a screen print.

This morning, I could not duplicate the running error with 2.5.4. The app, as before attempted to run, but didn't produce an error.

Next I focused on jt9.exe running in the back ground using the Task Manager app. Nothing found

I did find jt9.exe in C:\WSJT\wsjtx\bin.

At this point, I stuck!
