Hey @Kaustic_Kraken. 
Which version of the game do you have? Standard edition or remastered edition? Because I’ve seen you replying in threads for both and used the word “trainerS” when there’s only one for each. You need to make sure you’re using the correct trainer.
If you have the remastered edition, use this trainer right here.
If you have the standard edition then you need to use this trainer instead: FINAL FANTASY VIII Cheats and Trainer for Steam.
And also ensure your copy of the game is legitimately purchased from Steam (ie not cracked nor bought from a different store). And is up to date.
