Some of the modifications made by our modding community are not updated to the latest version of our game. On the latest version of our game, we fixed a bug that caused some of the Steam Issued Activation Keys not working properly. If you are trying to play a modification that is not up to date or requires the player to install an older version of the game, the new keys are not going to work. It is up to the mod team to update the modification.What to do with mods that require an activation key, but I already activated the key
Unfortunately, we can't provide any support for issues that occur with modifications for our games. Your best chance of resolving an issue with a mod would be to contact the mod developer directly, or by creating a post explaining the issue on our forums in the relevant section.
Is there a way to make an old key work on Steam? My old key does not work on steam. Thanks.1) You can acitvate your Steam key once and it will be added to your account.
2) IF you bought the game from our Webstore you can use the serial key to add that game to the Steam account. IT should work on all the game keys. Some of the Old M&B keys might not work.
3) Not in Early Access.
It depends how old and where did you buy the key. We can't support all the keys sadly.Is there a way to make an old key work on Steam? My old key does not work on steam. Thanks.
