There may be one other way to get this to work; we could try to crack the PAK file in the game's assets (WindowsNoEditor\FallenDoll\Content\Paks) and repack it unencrypted, and use the v1.29 non-DRM exe to run it. I don't know if that would necessarily work, but it just might.
To do this, we could use ALuigi's QuickBMS tool with the Unreal Tournament 4 plugin, found here:

(The plugin is toward the bottom of the page, and you would use the 4GB file version of QuickBMS included in the tool download), and then repack it with UPak4 (

There is a forum thread here where they're doing something similar, maybe reading through this thread might give someone else a better idea of how to get that key (I have no clue):

EDIT: Here's a tutorial on searching for that key, but it looks like to get it to work you'd need a working/licensed version of the game to begin with:
