Hmm, that is strange. I had a steam download with the other 2 DLC's and everything was great. I didn't play in a week or so, saw the new DLC on steam, d/l it, saw a new update came out, d/l the new CH trainer, and lots of CTD's. Maybe it's related to new GEForece Experience options that were enabled, but I doubt it. It played just fine without the trainer.. IDK.
So I have a little MS Surface I ran the game on, steam d/l all DLC, the trainer works fine.
But on my main PC with graphics card and all the trim, the trainer is still crashing out.
absolutely no idea why. I uninstalled and redownloaded the game, trainer, etc.. tried all the troubleshooting steps.. I guess I'll just have to wait for the next patch and trainer update to see if that will work... perplexing!
