Login credentials expired

So I have Xbox Ultimate Gamepass and Im trying to play NHL 14 with a friend, but when I try to play online it tells me that I need to reset my password and that my login credentials have expired. When I try to login to reset my password it does nothing. Clicking continue on NHL 14 on the Xbox just tells me that an EA account is required to play. So, I then tried to link my Xbox account to my EA play so I could play with the friend, but it proceeds to tell me my account is linked with another email. Im confused as to why Xbox sets a random email to Xbox Ultimate Game pass holders. The email its gives me is 7d*****@disabled.ea.com. I of course cant see the rest. I tried putting a case in, but it wont even give me the option. Im just so confused.
