Fix checksum failed on Assetto Corsa

A popular issue on Assetto Corsa is when people get the red screen with the "Checksum Failed" error.

The "Checksum failed" error happens when the server and your computer have different information about a mod. Each mod has a file on the server called data.acd, which holds details like power and grip. If your mod doesn't match the server's data, you'll be kicked out to prevent cheating.

To fix this, try deleting the mod on both the server and your computer, then reinstall it. You can also change the mods used in the event to figure out which one is causing the problem.
