Zombie trainer not working

I downloaded the zombie trainer file and i opened it and did all the steps but for some reason when i open bo3 it wont start and then a message pops up saying "bo3 didnt shut off properly last time do you want to enter safe mode?" im new to bo3 hacking and im probably doing something wrong so any help would be appreciated thanks

Hey, i had the same issue and know how to fix.

Step 1: Move the application from the folder to your desktop.
Step 2: Rename the application to anything u want that doesn't include any of the words "trainer" "zombie"
Step 3: Open bo3.
Step 4: Open the trainer from your desktop.
Step 5: Enjoy!
