Attempt to fix crashes to desktop with a new track 3do . This will not affect / alter the driving surface / layout, just the visuals.

Please place this in your c/SIERRA/gpl/tracks/AAIOM folder. 

This will not overwrite the original track 3DO as that is contained within the Dat file. Gpl will however use this newer one in preference to the original, unless and until you remove this new one.
