maya animation -> egg

Hello
i exported animation from maya2008

maya2egg2008 -a both file.mb -o test_run.egg

it is strange legs looks fine
but others parts are not correct

what can be it?
How can i fix it?

maybe someone will need it

i found how to avoid it. Do not know maybe it is not a good way but it works

i had 14 frames ( run )
i added 15 frame for zero position and exported the file. I got correct egg animation.

i corrected some parts of my animation and try to export it but ive got problems again so i added frame 16 save maya’s file and export it (now it is correct )
