Yup…mine is also Freezing in a couple of projects on start up and I have to use Task Manager>End Task and reboot Cubase too.
I can’t preview files in the right hand MediaBay pane…I have to Favourite a folder then navigate to the Favourites Folder and the Folder I selected as a Favourite and then open the contents before any of the contents will play back. Navigating to the folder on my drive in the MediaBay side pane will not open them.
