Crashing at log in

When ever I try to log in SL either crashes right as the client window opens Or if I am able to put in my user name/password and press connect it just tells me "Unable to connect. No Reply from login database. / Please try again in a few minutes, or click Help for advice and a link to the system status web page"

SL seems to be up and running. Why cant I get in?

EDIT: For some reason it is only doing it on this account, i can log in on my alt.
