SBFX & North Finance Demo's Not Working

I have MT4 demo accounts with both SBFX and North Finance. As of yesterday, neither are working. SBFX connects but just sits there with the Waiting for Update message and North Finance display charts but says Invalid Account. Have either or both of these brokers changed their policy on demo account expiration? I tried downloading a new copy of SBFX, but it made no difference.

I have the same problem with NorthFinance. But their client support does not aknowledge this problem. They say it is on my end, even though I can see the platform when I launch it, but as soon as it connects with the internet it displays a message saying that it has crashed.
