Using Movie Studio 14-148 on Windows 10.

I had Boris BCC8 on my computer from MovieStudio 13. I am now using MS14 and it was listing all the outdated transitions, etc. from BCC8, so I uninstalled BCC8 which had never been activated since it was trial-ware. Now I cannot start MS14 unless I say OK to hundreds of errors as MS14 looks for all the deleted files and folders.

I tried to reset MS14 but that did not clear the plugin list. If I remember correctly there is a file I can delete to cause MS to re-register the plugins, but I cannot find any posts which gives me the name or location of such a file.

Is there such a file, or do I need to delete MS14 and re-install?

Any suggestions would be greatly appreciated.

Thanks
