Odd error message

So i was just playing in an FFA and all the sudden the game exits to the login screen with a message saying,"10303"

what gives? ive never seen it before in my life!

I am not really sure I follow...but I have dealt with a lot of wr errors before so maybe you could post a screenshot.

OR is this the kind of error you are getting?

EDIT: You could also try this

Yup. the first one you posted is it.
