Client thinks my account is in game when I log in?

For some reason when I try to log into my account, it tries to put me in game but instead of bringing me to the loading screen, the screen just stays black. When I tried to close out, it asks me if I want to reconnect to game. I thought maybe someone hacked my account or something, but when I went onto another account of mine to see if it was actually in game, it says it's offline...

Anyone run into this before? What can I do to fix this??

Thanks.
