IB option chains when market is closed

Can you get IB's option chains on weekends even though the exchanges are closed? I'm not getting any, but I seem to remember getting Friday's closing prices throughout the weekend.

 

I can't even log into IB TWS from midnight Friday until Noon on Sunday. I assume everyone else can't either.

When you can log in, you can usually see the latest quoted spread. If that's what you mean?

 

I can log in without a problem, but all I see are question marks, which seems strange to me.

 

Yes, I tried that too out of trading hours, and got nothing from IB.
I believe it's possible, and I would like to know how to do that too.
Thanks,
