I'm sorry to ask but: how were you able to play before, since you created your forum profile today? Patch or not, don't you need to register your key on the forum before you can play? 
Hello Gab,
In my opinion, it is not a hard and fast rule that one has to join the Forum to be able to play the game. During the installation of the game, it will at some stage ask for the license key. Once this is entered, the installation continues and is eventually completely installed. The simulator is then ready for use. If you see the System Requirements, it does not say that membership in the Forum is mandatory. The same holds for the patches too.
You can join the Forum without registering the License Key but you will not have access to all the boards. It is for this reason we encourage members to register all their SS products. I have seen quite some posts which is a member's first one and he is asking for a solution. That does say he has used the simulator for a while and then discovered the existence of a Forum which he joins. It is left to the choice of the legal owner of the product about joining the Forum.
However membership with the Forum is required for joining 'Multiplayer'.
