Error importing .nif into Blender 2.49

Hello, complete noob to all this here!

Im trying to import a .nif in attempts to mod a skryim armor. I set everything up accoring to this page:
and everything seems to have installed just fine. I modified the appropriate settings in NifSkope per the tutorial im working with, and i’vw matched the options they show for importing the nif in Blender, but when i hit the final ok to import, i get this error in the console:

Traceback (most recent call last):
File “D:\Modding\Blender Foundation\Blender.blender\scripts\bpymodules”, line 1235, in gui_button_event

raise ValueError(‘array too long (%i)’ % len1)
ValueError: array too long (4294967295)

Any insight as to what is going wrong here would be greatly appreciated (especially if you can keep the wording pretty simple, i have literally zero experience with both python and blender)
