I have that same error. Havent found any fixes sadly 

Windows 10 Asus Laptop (potato)

Update: I can't seem to find a solution so sadly i think on my bigger desktop computer i'm going to have to literally re install black ops 3, THEN re-install mod tools, THEN re-install the extra crap that you need. Frankly i'm really pissed right now at 3arc.
Thanks, 3arc.

Okay so if any of you could try to figure this out that would be awesome. Anyway, i downloaded Black Ops 3 mod tools and im exited af to make some dank zombies maps bc i am a waw mapper too. i open up launcher, make a new map, then i try to run radiant. when it opens, it gives me this:



i have no idea what to do. Please help!!

dude, i feel you because i have same EXACT error and i have no idea what to do. ill try to make another post and if i get a response ill try to tell you.

My mod is not running.

So recently i started working on a new map. Then after creation, i watched treminators tut on how to install ugx mod. I did everything correcctly, but when i run my map it says "Couldn't load image ui_invite_new"
