====== When entering a game I get the message that the host has a different patch level. Why? ========

The complete message from Settlers 3 is:

"The host has a different patch level. Interaction not possible".

This message appears if you are using a different Settler 3 version than the host. For games that are started via the aLobby, this can only happen if you or the host have an older aLobby version running.

**Solution:**

Both the host and you need to update the aLobby. See [[en:faq:wie_aktualisiere_ich_die_alobby_auf_die_neueste_version]]

**Background **

The aLobby takes over the handling of the settler 3 version for you so that all players have and use a uniform version of the game.
