Enabling Macros

I recently downloaded a software programme that was supposed to enable me to print some Business Cards. Having designed the cards, when I tried to print them, I got a window saying that my Macros were disabled (sounds sore!!). I have tried everything, but just cannot work out how to enable them. Can anyone help. I tried the 'Help', and it said to close the file and reopen it with Word 2000 programme with macros enabled. I just can't work out how to do this so if anyone can tell me, please give me step-by-step instructions.
Actually, I tried to print Business Cards through Home Publishing, but as it doesn't tell you which Avery cards to buy and doesn't give you any options to change the settings, etc., couldn't manage that either!
Happy Christmas to all from cold, frosty Ireland

 

Thank you, Steve. That worked just fine.
