In Vegas 9d, I got the following error opening my current project. Rebooting did not clear it, but older projects open without the error:
An error occurred while creating a proxy file for a stream.
Error 0xc00d002f (message missing)
I don't see any reference to this error in the Knowledge Base. It affects the waveforms which should be visible for the project audio, although the audio plays on all tracks in preview. I have not moved any of the project files.
Any ideas?
