Dashboard Admin Problem

I have searched the forum and can’t seem to find anyone else who had this situation.

Looking at my blog today, the format is messed up. When I try to log in, it does not recognize either user name or password. I have them both written down and have been using them.

As I previously used a wordpress.com blog, careerintervention.wordpress.com I can log into my global dashboard from there. However, when I try to switch to blog.careerintervention.com it doesn’t switch over, but stays in the wordpress blog instead of the one at my url.

Nothing has been changed on my sites dns or admin. Could I have done something on the dashboard domain manager?

blog.careerintervention.com
