I'm sure John EB will reply also, but my initial reaction is that Movie Edit Pro 17 Plus HD is actually now an "old" version which may well not be able to run under any recent version of Windows 10.
If you wish to try another uninstall and reinstall, since the previous attempt at this was at least partially unsuccessful, please follow exactly the procedure in this tutorial.
We are still missing some information, in particular your Windows 10 version.
However a good guess would be that you are on Windows 10 version 1803 or 1809.
The program is not compatible with Windows 10. I have had some issues with it on Windows 10, various functions did not work and the Windows 10 1803 update finally stopping it working altogether.
