I have the GOG version. I've applied the patch and installed the DLC. The trainer is working fine, at least everything that I've tried anyway.
One word of caution. I always customize my keyboard controls and after installing the above, the KB controls have all gone back to the Default settings.
Other than that, seems fine to me.
Thank you the trainer seems to be working perfectly now I thank you for the time and effort that you and the rest of the CH team has put in.
