I created a WLID a few years ago, as I had a Zune. I also bought an Xbox a few years ago, but never hooked it up to the internet / Xbox LIVE.
I now have a few games I want to purchase some DLC for. Unfortunately, I can't seem to sign up for XBL on my Xbox under the avatar I've used for years with the WLID I've separately used for years. I keep getting a "This Windows Live ID is associated with a different gamertag. Enter another Windows Live ID and password." message.
I can't seem to change my avatar/gamertag's name to match my WLID's name, nor can I seem to change my WLID's name to match my avatar/gamertag's name. Any help would be appreciated.
