Problem resolution: When I first uninstalled the SBPro Software, I made no effort to manually remove all of the esim folders on my system and the problem persisted when I reinstalled the software. I just went back and removed all of the esim folders I could locate on my computer, including on OneDrive, and then reinstalled the SBPro and Codemaster Software. The SBPro software is now up and running, to my great relief. Many thanks to all of you who suggested strategies to resolve my problem.
