I've used versions .37 and .38 of RoR, and have been able to download all tracks from SM no problem. I can also download/use trucks from the main V4 pack ONLY. I can download and install all other trucks on SM, but when I go to choose them in-game my screen freezes and I'm forced to sign out of my PC. I've tried different things in the past to try and fix this, but so far nothing has worked. Any help is greatly appreciated. Thanks
