I downloaded those scripts for Blender, but when i go import/export something using that script, or any other else, its says something like that:

Script error, see console.

I go see the console, but it says:

No such file as C:\Program Files\Lucasarts\Star Wars JK II: Jedi Outcast\GameData\data\assets0\models\wheaponhits2\blaster_r\blaster.md3

Why?

PS: I unpacked the assets0.pk3

PSS:I downloaded a MD3 Script for Blender
