Q: Why do I get a -25001 error when I try to register MacGourmet?
A: This error usually means that you have entered your serial number incorrectly.
Make sure that when you enter your serial number that you enter it exactly as it is listed in your confirmation, make sure you enter zeros for zeros and the letter ‘O’ for the letter ‘O’. That’s the most common problem people seem to have, and once they fix the entry problem, they are usually all set.
It’s also usually easiest to just copy and paste the serial number from your confirmation email into the serial number field.
