This seems to happen at random when I make an .exe file with included media. Some people get that error, some don't, and there's not really any logic to it.
Here's a *possible* explanation...
When you run an .exe with included media, the program unpacks the media into a temporary directory and then loads it in from there.
Maybe DBP is not able to unpack the files quickly enough to get them all saved, or maybe it corrupts some of them as it unpacks them.
Or maybe they were corrupted when they got packed into the .exe, I don't know.
What I *do* know is that making an .exe with included media has NOT been a reliable method of distribution, for more than one of my projects.
