Error: Unknow property "x" identified. Help.

I keep getting this error when i try to export my model: Unknow property "x" identified.
What does that mean and how do i fix it?
Help...

I remember something like that happened to me along time ago. I do believe it was max 4 using KMK's static importer/exporter! I had to upgrade to max 4.2 to fix it if memory serves, hope that helped!

Also, try and add details like modeling app, script name and such to a help request, it helps us help you
