"DIGMID patch set not found" (SOLVED, probably)

[EnterTheStory (aka tolworthy)]

I just reinstalled Windows, tried running the last build of my game (using 2.72), and got this error message: "DIGMID path set not found." I think this means Windows cannot find any MIDI sound players. But my game doesn't use any MIDI (as far as I know).

How can I make sure my users never see this message?

Edit:
I just found that it's a more general problem with my computer. But I'm still interested in knowing how I can modify this kind of error message. Can I check if sound works then show a message of my own choosing, instead of the Windows default message?

Have you tried disabling MIDI music in the Winsetup?

No, but I will... as soon as I can rescue my main machine. To cut short a very long story, I am currently unable to install Windows at all, so MIDI is no longer my main worry.

When I'm having problems with modern technology, I usally find that a shotgun blast at point-blank range does the trick..... or you could always try shooting the computer, instead.
