Not sure, just guessing, but is your game updated to the latest patch before the 1.17.5.1 patch (if my memory doesnt fail me, the patch were named 1.16 something). Not sure if the 1.17.5.1 patch is a full patch...
Also, are you using the correct patch made for your game (earlier patches were depending on which publisher published the game)?
