I've been using the 4-7-2014 Trainer the last few days and it's working perfectly. Something else is causing your crashes. Are you running both game and Trainer as admin and turning off your A/V and firewall? Make sure you get rid of any old versions first then dload the newest 4-07-2014 trainer and/or editor.

Well, Giddy-up then! I like to run the trainer and editor together. Have fun bro.
