When I attempt to open and play a new project to replace my current one by selecting a new project from the File menu, or even by first closing my current one before I select a new one from the menu, I get this popup after the new project opens:
An error occured while starting playback.
The request is not enabled for this device.
To open a new project I now have to always first close Vegas down. This has never happened to me before with any any of my older versions -- even now I can open one project on top of another without having to close my Vegas 12 version, so I don't think it has anything to do with my "device", a fully equipped desktop with lots of power and memory.
Can anyone here reproduce this this for me?
