No idea if it will help but in similar situations I've had luck with clearing the cache and cookies for the site and then reloading.
If you are on a PC/Mac in most browsers you can bypass the cache by holding ctrl before hitting reload.
If bypassing the cache doesn't work then you may want to move on to deleting any GiantBomb specific cookies. BE CAREFUL though. If you delete all your cookies by mistake you will inevitable be logged out of some other random website that you don't want to be logged out of.
