So I thought I would make a thread of some of the know problems and some of the things people have done to fix the issues. All of the below text is from either Nvidia forums, Bethesda forums and FAQ's and from Steam forums.

It is try at your own risk, but maybe you can see the problem here and get an idea of how to fix it, or maybe you will find out that you just can’t run the game.

You can also try and enter the Bethesda.net settings menu in-game and claim items by selecting Reconcile Entitlements.

Exultia Slayer Key not there.
It is reported that if you have enabled cheats on ANY map, they keys will disappear from ALL maps. Even though you don't have cheats on the map you are playing. Its also being reported that removing the cheat, and just starting the map again, does actually NOT remove the cheat. You have to start the map, exit, press mission select and remove the cheat before you start the game. This is not confirmed.

The launcher simply does not support it yet.

Multiplayer
Constant disconnects with "unable to contact game services" error
Posible fix: Windows 10 users, make sure everything is updated, and the game whitlisted in the antiviral program / firewall. Win 8: Theres a theori, that Win 8 players can't use multiplayer because of missing DLL files. Sadly the only soulution is to upgrade to Win 10(This has been confirmed by several users has worked).

Solution: Go to Control Panel on your computer, "Internet Options", select "Advanced" tab, go down to "Security", enable "Use TLS 1.2".

My save game is gone or not working.
Solution: This require you have allready had your save game backed up.
