Hello,
It could be that your path from root (C: or D:) to your file is not MSdos savy.
Avoid any space or non pure ascii characters in all your path.
Most of time is the reason for TD not fiding the file, even if you double-click on it.

Jacques, you nailed it. TD wasn’t able to read the path to the project file. Changing my OS language to English and moving the project folder to drive D fixed the problem.
