I checked out the other help topics, but I'm not sure what my problem is. I'll give the details here, thanks in advance for any help.
-I created a profile on the actual game. I'm assuming this is totally unrelated.
-I tried to join xbox live on the screen. It asked me for my email and password, but it didn't work when I entered them.
-I tried to join xbox live on the site, with my normal email. It said I already had a windows live account. So I said I forgot my password, but then Windows Live said there was something wrong with my User ID.
-Failing that, I created a new xbox live account with a new email address. That worked.
-Then I tried signing back on my tv screen with the new information. It said "this windows ID is associated with a different gamer tag."
-I went back online and changed my gamertag.
-Same error on the screen. I didn't think I even entered a gamer tag, so I'm not sure what happened.
Again, any help is appreciated.
