I wonder what version I have, too.
Looking at the update page, I get this info-
Patch notes for version 2.31:
This update adds 5 new liveries and one new long distance model created for PCPilot. It does not contain any other update.
... also, file dates are 2007.
I wonder what's contained in the previous update, 2.30?
