Verifying the game cache can be useful if you are having technical issues with your game. This process checks your game install folder and compares the files to the files on the download server to look for differences. If it finds any issues with corrupt or missing files on your install folder, Uplay downloads and repairs those files to your install folder.
Note this is only available on newer Uplay titles!
1. In the Uplay client, click on Games.
2. Click on the game you wish to verify the files for. You will land on a window that looks like the one below. Click on Properties and choose Verify files.
3. Uplay will then begin the process of checking your files.
