Taken verbatim from this post (https://blog.activision.com/t5/World-at-War-Forum/DW-profile-update-error-102-BD-EXCEPTION-IN-DB/td-p/10664987): "But myself, along with my friends and many others on the Steam community discussions have been receiving this error all day when we launch the game and the game attempts to connect to the servers.
And whenever you try to close the error, it just keeps popping back up again which prevents you from clicking any other actions, and thus makes the game unplayable."
Workarounds available yet?
