I just got the game off ebay, it was used, but I got the info. And I Dled the game when I got the guest key, reinstalled it, blah blah. yet when I look in the editor, I can't find any of the campaign units... and the unit pallete still has all the random lemon shit.. Whats with this?

File -> Dependencies -> Add -> Campaign.
It's as simple as that.

Wow dude! I love you!

It's not that simple, if you actually want to edit something because the campaign dependency has to be on top of the list...
