AiCola: so you were right it kept going but it gave me an error in the end.
should i reinstall the game?
Will my saves be fine?
Errors were due to the fact, that some files were patched on the first run and thus patcher couldn't find these it was supposed to patch (there were different than what it expected). To be on a safe side and to avoid problems with future updates, you could reinstall the game and then apply the patch (it takes so long, because all main files - ~20GB were changed in the new version).
Saves were unaffected by the update, although it is a good practice to always make a backup just in case.
