Yeah, I've experienced a hell of a lot of crashes. I've played the game with and without the trainer, so I know for sure it's not the trainer. So the patch is needed to make it playable, but if they're going to patch it, again, in a few days. Let's not ask CH to update the trainer for such a short span of time. Let's be patient (or simply not update and use the current trainer )
Only thing wrong with waiting for the next patch before a new trainer is how often do game companies release a new patch the day they predicted they would? I can't count the times I've waited weeks or even months past the predicted patch release.
As far as waiting to update it's too late for that if you use Steam. My initial download/install today seems to have the new patched version.
