Lancair Live!

I'm hoping to get my IV-P back from the avionics shop soon with a new panel anchored by GTN750xi and two G3x's. I recently downloaded the Aviation Checklist Editor from the Garmin website intending to incorporate my check lists into my G3x and GTN 750xi. The download went well, but it does not come with any instructions and my plunking around on the keyboard and guessing how it works has gotten me nowhere. Garmin only includes disclaimers pointing out that if it doesn't work it's not their fault. Does anyone have any experience with this software and can give me some hints on how to make it work? Or, and alternative.

Thanks,
Ken Kellner
