Do you have any custom CSS or addons to your Chrome browser that could be blocking it? Have you tried another browser? I am having no problems in starting a game or ending it.

Ok thanks for the answer. I will see what I can find out.

I heard back from the programmers and they said that blackout is one of the games that is going to need an entire rewrite. They tried making fixes before and had to roll them back because it made the situation worse. There is no ETA on the rewrite but for now they are working on moving things over to the new site.
