Just tried to start a new blank scrapbook and got this

Scrapbook MAX! encountered an error (28) unzipping the following file:
C:\Program Files\Scrapbook MAX!\Templates\Blank Scrapbook.smt

I've tried re-booting to see if that helped but no.
I can open a design template though, just not the blank one.

What is error 28?
Does it send me into a black hole if I try opening it too many times?

Thanks for your help in advance
Sue
