Hey! I've recently been forced to switch to windows 10 for a couple months, coming from Ubuntu, and i can't seem to figure out how to use 3420. I've downloaded the game on steam, but whenever i try to launch it (through the Portal.bat), a CMD window opens for 8 seconds, another window flashes up and then closes immediately, followed by the CMD window closing after. It crashes on launch. The base game, and the source 2.4 version, launch fine. If someone could help, that would be much appreciated! If there are any logs that i could submit, please point me toward them so i can upload them here. Thank you!
