Unable to login after playing the other day

I'm not sure whats going but i can't log on. It stays on the Connecting screen for a while then it tells me that i have to switch my account to battlenet account. At first i was thinking maybe the servers down but i can see others are online. I've done everything that i've seen on the forum, ex. deleting cache folder, delete WTF folder, make sure the config tile is SET realmlist "logon.warmane.com", reset DNS. Is anyone else having the same issue? Its just odd because i was playing the other day. Not sure if this has anything to do with it but i noticed the other day that Warmane showed up on Credit Karma (i've since changed my password).

Does anyone have any ideas?
