As games are starting to get bigger and bigger Steam has a special feature that allows you to verify game files without having to uninstall and reinstall games to fix problems.

To Verify Game files you will need to do the following.
- First open Steam.
- Now change to the Library tab.
- Here find the game you are having issues with and right-click on it and select Properties.
- Change to the Local Files and click Verify integrity of game files.
Now just wait for the process to complete. It can take a considerable amount of time for large games.
Uninstall and Reinstall the game.
If verifying game files didn’t help solve this problem for you, you will sadly have to uninstall and reinstall the game. If you have data limits this is going to be super frustrating however, there aren’t really many other options to help solve the problem.
Uninstall and Reinstall Steam.
If verifying game files and uninstalling the game still didn’t help solve this problem, you may have to uninstall and reinstall Steam on your computer. If you have quite a few games installed this is going to be a pain in the butt especially if you also have to adhere to download limits.
Note: Before you start this process, you may want to consider making a backup of your Steam games (the ones that are working fine) or just move them to a different location on your computer. This will save you from having to download all of them again.
