Getting export error for KF/Nif files Syntax Error Anim Buffer

[Xolerys1]

Hello, currently ive run into a wall trying to export a reload animation im doing for New Vegas. Im following this tutorial by ShinyHax https://www.youtube.com/watch?v=YU1TwnzYuw4 Im all done with the hand movements and baking and settings the priorities basically im at the 1:20:56 mark. But when i try exporting as a kf file, i get a error message Syntax Error Anim Buffer. I have no idea what to do. Im running Blender 2.49b , Python-2.6.5, PyFFI-2.1.5 , blender_nif_scripts-2.5.5, and nifskope-1.0.22.
