Can you get those charts in TWS? If not then the server is probably having "issues".

 

I get that occasionally when I am running on either the demo server or my paper account. It seems to happen more in the Fri/Sat/Sun time frame, so I'm wondering if they are monkeying around with the system at that time (markets closed). Haven't seen it during open markets on my live account, though.
