Baffled you keep trying different buttons in the church software, check the manual and eventually apologize to everyone for the failed demonstration. Embarrassing you admit defeat and ask them if they could give you some time before the next demonstration so that you can figure out what went wrong. You can not have this happen during the regular church services—everything must be perfect for that!

Then, someone at your failed demonstration casually mentions something that you never thought about. "Is the software in the new projector compatible with the software in the laptop computer?" What a brainstorm—why did you not think of that before attempting the live demonstration.

Now it is back to the operating manual of the church projector to read more about its software package and what type of computer software is compatible.
