If you reported the game needs an update and it was denied as working then one of two situations are most likely.
1. You did not provide enough information for the issue to be replicated. For example if you have to be past a certain point ingame, or in a unique situation, only happens when certain combinations of trainer options are used at once.
I always recommend reading this
Link Prior to putting in an update request.
2. The issue wasn't able to be replicated on our end. This could be for any number of issues such as the reporting user having a: Corrupted game file, Antivirus not set to exclude, conflicting software, using pirated software, etc. In short the answer is on the reporting users side not an issue with the trainer itself. Therefore a trainer update wouldn't solve the issue. User would need to find out what's preventing the trainer from working as the trainer is working as intended for others.
Be advised that people rarely post when something is working normally and as such most posts are going to be in regard to issues. That's not to say we ignore issues, just stating that if only 2-4 users out of the currently 276 people who've downloaded the trainer have an issue...it's not always a trainer issue. Which is why the 3 update request minimum is required.
This post was designed to be informative in the most likely causes of the issues your running into. While the above mentioned are the 95% likely scenario, we are humans and can make mistakes just like you can. Just be aware it happens incredibly rarely.
