wtf is error code 122?

i charged AC, only to wonder why i didnt get the AC hours later
so i relog on ES, and reauthenticate

log in, see zero AC...
log out, and there is this local account thing i've never seen before
log in local account, there is my 5150 AC
try to link account, get error 122

WHY.
HOW do i get my AC off my ES????
this is so stupid, how is this even a thing.
