The new (updated and hopefully stable) distribution of files is located at the bottom of this post.
New in this release:
1) Code now accommodates variations in FFmpeg log file formatting, which is required for building the conversion progress bar.
The paid-for version of the app is not affected by this issue because it already recognizes variations in FFmpeg log formats.
Thus, the full version of the software will continue to function as before -- perfectly!!
As always, please let me know if you have any questions/concerns regarding the above and/or the code.
