I'm having the exact same problem. I own a registered copy of v4.02 which goes through the motions of burning a disc, as per the initial post in this thread, and then there's nothing on it.
Also since installing Express Burn as part of a total NCH package (Swift Sound suite) I purchased a good while ago, it seems to have taken over my 2 Pioneer CD/DVD burners such that Windows now doesn't recognize a writeable disc when it's in either of them anymore.
Not happy, Jan.
Anybody got a resolution to this "ghost burning" problem yet?
