64bit. Why is that a bad thing D:
It kinda stuffs us up. You're trying to run a 32bit exporter on a 64bit program, a year above the level it was made for.
Only thing I can recommend now is to try and find a "max2dts" exporter for 2010-2012, which is 64bit. Your best bet would be to post on the garagegames forum, under the artist discussion board.
