There is currently no official download, so there's no link we can provide you to the game's installation files.
It would be easier to try fix your error, but we can't do that without knowing what the issue is.
If the game wont start, check out
forum.helloclan.eu/bfv/10
If you can't find the server, visit
forum.helloclan.eu/bfv/direct
If you get banned when joining, you need to reinstall as a file may be corrupt.
If you can't connect to the server, you're running the wrong version (the server will be greyed out on the server list) and either need to update or reinstall, depending on if you are on a version below 1.2 or on 1.21 respectively.
In the former situation, you can download the 1.2 patch here:
