Hello,

To replicate the issue, add a project to VCC from an external HDD/network path/USB pen/etc.

Close the project, remove the external drive.

Try to add again a project to VCC.

Because its trying to open the last path (that doesn't exist anymore) it fails to do so and just trows an error that no valid projects found, without opening an explorer window.

This happens every time, the solution is to reconnect the drive. Press the Add Existing Project button again and move to a valid path. Then you can remove the external drive and the since the last path is valid it will work again to add another project.
