Help With Running Certain Programs

[That BattleToad PSA Guy]

I got Blender, DasDonkeyBox and Anima8or. But I have a problem with each.

Blender: Won't read Brawl .pac (Which I know, but it leads to my next problem.
DasDonkey Box: Gives me an error that says "The main startup class was not found", which means I can't make the files Blender-friendly.
Anima8or: ...I DON'T EVEN KNOW HOW TO USE IT!!!
