It's probably a basic pointer driven trainer that doesn't work for all users across all OSs. Regardless, if you found a better trainer, use it. We have infinitely more games to cover than every other trainer maker on the planet and cannot invest the additional time to 2 different trainers for this one game including every patch that will be released over the next year.
I prefer CH trainers always. Getting a trainer from elsewhere was my only option because I can't play 32bit with BF4. The trainer I found works with version 1.0 and the patched version of BF4. I only have windows 8.1 so I don't know if the trainer I found works for all os's.

My trainer quit working, Origin loaded a big update when I started the game today.
Yup, they just ran another update. Be patient and the CH crew will have a working trainer shortly.
