As soon as i joined the server i got the checksum failed error and got kicked out.
After a few tries, i tried to verify the integrity of the game with steam and updating the track while qualifying was going on, but even after that, i wasn't able to join.

You use the wrong version of Watkins Glen mate

I updated it and it still gave me the error.
Now i'm fully reinstalling AC to see if that's the issue.

Don't update tracks. Reinstall tracks. I'm fairly sure if you just overwrite what is there with the latest, it'll leave shit that will still cause a checksum error.

As Russel said, re-install. Meaning, go to your 'track' folder, delete Watkins Glen. Then unzip/rar the correct version in the track folder and you should be off to the races (pun intended   )

I see. I guess it's one of those things that has to happen at least once to learn from it   

Thanks guys.
