That was not my experience. I played the game thru about 2½ times and didn't have those issues using the previous version, #5 for I believe it was 1.5.1., on Steam.
That and on the previous page, the trainer creator and another member reported the trainer working fine, 100%.
Just be doubly sure to dload the correct version and if you do have those issues, use the report form that Pwizard posted about 2 messages above yours.
Well, since my play was on the previous version, I can't speak directly on issues concerning the newest trainer.
But given the choice of what to listen to, a random user having issues or Caliber, one of the absolute best trainer makers on the planet saying it's working just fine, I have to believe Caliber. And since other users have reported it working fine, too, that makes one think the trainer is working as intended.
Can problems occur? Yes. If they do, use the Trainer update report Pwiz mentions.
