Is there a way to play earlier scenarios?

Apologize if this has been asked before...just found some really cool scenarios at Rugged Defense and I can't open them with my Matrix version. Any help appreciated, thanks.

You can convert the scenarios designed under the ACOW to TOAWIII by opening and subsequently saving them in the editor.

If you're interested in scenarios from earlier versions, I'm sure there are some good souls over here who own both ACOW and TOAWIII (not me unfortunately) and are willing to help you out.
