Hi I have the same problem I have a lot of projects and when I go to open them it has a large question mark where the video thumbnail is on the edit timeline. I captured on external HD and have since switch on different usb hds and think the harddrive has the wrong name have tried switching on and then connecting the right hd with nothing else connected but no joy at the moment. Is there any way off tracking the right path for a project? or is there something else wrong.

 Thanks for any help

PS will be away for a short time back on Wed so will be in touch then, Cheers
