Normally I would help you out being that we are in the same league. But because I like you ill give you the hot tip. With your first draft pick you need to take Tim Tebow, honestly the best QB in the league
The same happened to me. But after I registered, I headed back to the fantasy homepage. There was a button somewhere for joining a league. Took me to a page where I could enter the league ID and password and I was able to get in. Hope this helps!
