That sounds like a bug I've heard of. Did you get a quest from the guy who's supposed to give you an assignment for Joining the Stormcloaks? That's what usually triggers the bug I'm thinking of, where Ulfric will tell you to go to the other questgiver, but the other questgiver will tell you to go to Ulfric. I haven't heard of any fixes except to start a new game, however.I have a bugged quest in Skyrim which is a major part of the game. It's called "Joining the Stormcloaks" and basically Ulfric tells me to talk to some guy for an assignment, but I can't even open a conversation with the guy who's supposed to give me an assignment.
