Need help with Hobby Lobby templates for place cards please!

The product key should be somewhere on the template box or in the instructions. Where did you get the product key you've been entering from? If the one off the box isn't working for you then I'd return the product to hobby lobby and get a different one.

The product key is for the Windows office. I don't know why it's asking for one. The template is locked now and I can't use it. Thanks though! :0)

I'd just try googling it for support help. Not sure if any of this works, but I found this helpful link:
