You might want to include a little more detail other than " its not working" otherwise how could anyone possibly help you with the problem. When exactly does it crash? as soon as you load AC, when you click on the Online menu, once you have already hit the Star button ??? what other settings have you got set?, what are your computer specs. You cannot realistically expect anyone to diagnose a problem with " it just doesnt work" which is basically what you have provided..
well just taking a look at your errors log, it says right away where the problem is.. there is an issue with your Video config file " video.ini" try deleting that and reloading AC it should create a new one as soon as you restart, then you should just need to set your display options in the game again..
You can find it in .... C:\Users\vlodeck1\Documents/Assetto Corsa/cfg/video.ini
Cool glad you got it working.. it was something to do with the max frames per second. it looks like they might have changed how that works slightly but your config file was still trying to do it the old way.
