Hello everyone, I'm new to the forum, modding and Black Ops 3 (I know i'm a couple years late, but I've been busy okay!) and I cannot for the life of me get any mods to work other than a simple menu for zombies. I just really want to enjoy custom zombies and mods, and I feel like I've exhausted my options .

I have tried multiple custom maps, and other mods, only to receive a similar error code to this:
"
Error loading fastfile 'en_core_mod': Fastfile archive checksum (0x5AFFBD78 0xCCC83871 0x205192D9 0x2AB0E985) does not match executable nor any permissible
Except the highlighted text is different for each mod.

"
What I've done:
  • Restarted Steam, logged out, logged back in.
  • Restarted my computer.
  • Looked over dozens and dozens of steam, Reddit and forum topics trying to solve the problem by doing solutions to other problems such as verifying the integrity of the game files and etc.
  • Re-installed the game.
  • Verified integrity another dozen times...
  • Deleted and re-installed mods.
At this point I really have no idea what to do, hopefully someone can help me out. I saw that in another topic someone suggested it doesn't support my country but every single popular custom zombies map and mod doesn't support the United States? That can't be possible.

If anyone can give me any help or guidance that would be awesome, thanks again.

Here are some examples of the errors I receive:

Hello,
thanks for giving so many details to us. I'll assist you to get all the mods and maps running. First, are you installing the mods due the steamworkshop function? Or are you installing it manual?

Secondly which game language are you using? English?

Yes I have figured it out make sure you it updated to lastest version, if you dont have steam version like me you will have to download another black ops 3 with new version, then go into zone folder inside map and look for "workshop.json" right click and open with notepad. Look for folder name and copy it and paste the name on folder, it should look like this usermaps/folder name(copied from workshop.json)/zone

I had nonsteam v .88 and I had to download another blacks ops 3 version 100.00.00 and made sure I copied the folder name from workshop.json file, this is where the issue was for among us for me was the name, other discusions say you can name it whatever you want but it has to be the workshop.json folder name, sometimes its a different name than what the map is called.
