Steinberg had this to say:
"It sounds as your Cubase project is corrupted. In this case the easiest solution should be to create a new Cubase project after the tracks' exporting.
However you could decide of deleting the Cubase 4 Preferences folder and all its contents: I usually suggest it when the problem appears always.
You will find this folder at the path below:
Go -> User Name Profile -> Library -> Preferences -> Cubase 4
If you have some particular setting which don't want to loose it's enough you rename the folder "Cubase 4" with another name. Cubase shall create a new folder when it shall restart itself again "
this is fukin stupid!!!!!!!
i exported the tracks / included copies of the media files in the export / imported the tracks / copied media files to the project folder....
all the track data is there but no fukin audio files in the project window..
opened the pool, the names of the files are there but "?" next to all of them.
seems like the only way to get the audio is to hit "search missing files" and individually locate them from the external hard drive!
this is fukin stupid! i have way too many to do that.
its not even finding them from the original project file saved on the computers hard drive.
surely there must be an easier way to get the audio files into the region parts than this?
any help would be mostly appreciated
cubase.net forum may be a good place to post this.
