Old Storyline 1.0 zip files

You need the one that ends in .story 

I should've mentioned this - when I look at all of the files contained in the zip file, there are no .story files. Take a look at the attached screencap.

That's the published output. Unfortunately, you can't open that in Storyline (only in your browser).

Unless you can find the original .story file, you'll have to rebuild the course.

Thought so; appreciate the confirmation.
