As is usual when working on assignments; you move away from the main computer to work on the laptop to prepare for University, when Scrivener decides that the project cannot be opened with a Location Access Error. WTF?
A lot of Googling later, checking Permissions; Read Write access; etc. I finally traced the issue to BitDefender and its RansomWare Protection – which basically locks out several system folders from unwanted file access – including Scrivener’s need to use my Dropbox folder, since I use Dropbox to back-up and transfer projects.
Long to short: Kill BitDefender’s RansomWare protection – or take the time to set it to play nicely with Scrivener.
I’ll be glad to be shot of it for a better Anti-Virus.
