Originally, I signed up for xbox live with a Windows Live ID (WLID). In the future, I bought a zune and then signed up with a different WLID. Until now I never really thought about merging the two, but i have 80 Microsoft points on one, and 79 on the other. I tried following the steps to switch the WLID associated with the xbox live account to the zune's, but it says that I cannot because the other account already has an xbox live gamertag registered to it.
How can I get around this?
