Well, I had some problems this week, the quests were failing.
One friend convince me to make again the mod, starting by 0. Now I don't have problems with the quests anymore. I'm very happy because all quests work perfectly, and I have now five quests :)
Also, I made the Imperial General Armor and Stormcloak General Armor to work correctly in the game.
The first three quests lasts 30 minutes, and there are more than ten quests!
