Yes… I am an idiot.
Testing this out on a laptop. Applied an Administrator password. I am sure I know it… just not which of the many passwords I try to remember daily.
Considered uninstalling and then reinstalling but… you need the password to uninstall - even if you are an administrator on the computer.
We suggest you backup data first, and then fix mbr with windows recovery console.
After restart OS, you can uninstall ctm.
Hope it helps.
