Change your windows regional settings to US standard, yes that's right you heard me.
carcass doesnt like the metric system, if you dont change your settings carcass will report this error message:
"error, file contains cubic scale keys" and wont do squat with your file!. You also need to have your keyboard set to U.S. and remember to reboot when you change your settings."
Once you made the change, re-export your file and re-compile.
trust me, i've spent two weeks trying to figure out this one.
