Where did you find these MX9 files? I've never come across them before.  Are you sure they're for MSFS?

The only design applications I know that are compatible with MSFS are Gmax & FSDS2.

----IMPORTANT----
It's a freeware

NOTE! it says it will give an error, just hit the no button so the undercart shows.  This is not made using MX9 i think u got a little confused there.

I reckon you hit yes and its causing probs.

IT appears to have been one of Camil Valiquette's older models made with pre-gmax/pre-FSDS2, probably FSDS1.  This is the older model format that FS2004 does not fully support.  Given that it has SDLedit macros is the clue.  With FSDS2, and gmax, you don't need to resort to Mike Crosthwaite's excellent utility.
