Hello there, Recently purchased TS21 and was working fine through Steam. I then updated the graphics settings, going from Full Screen to windowed mode and now when I attempt to launch the game, it wont. I hit 'Play' on Steam, it 'Launches' then goes to 'Running' for about a second. Pressing Alt + Tab doesn't show the game, so the game is definatley not launching. I've tried uninstalling and reinstalling, same problem persits. I'd be greatful for any help.
Try deleting the player profile, and then re-installing Train Sim again. C:\Program Files (x86)\Steam\steamapps\common\RailWorks\Content\PlayerProfiles.bin
