im trying to link my xbox live account to my CoD account and it pauses then it acts like i never done it
Thanks for taking the time to post!
After you log in to your Xbox live account, does the page take you back to your profile page? It might be a cache issue within your browser. Try clearing the cookies/cache, closing the browser and trying to link once again.
If that does not work, you may need to create a new account using a new email address.
