6 yes all actualizations patches and stuff are downloaded

Sorry if this is what you meant, but can you confirm the actual expansion is installed? It doesn't come as a regular patch, you have to go into the settings menu (on the launcher, before you click play) and actually select to download HW expansion. There's an option to also automatically download expansions in future, but the first one you have to do yourself (or at least turn on automatic for it to do on next load)

What it sounds like you have is it registered to your account (because you can level past 50), but you don't have the actual expansion itself downloaded so the game is stopping you as it has no idea what to do next until you do. The main game patches for people without HW so they see the new gear/skills etc, but the expansion itself is a separate download for all the cutscenes, quests, story etc.
