Some symbols don't update Intraday

[John Nelson <trader@xxxx>]

All,

Forgive me if this is a stupid question but some symbols I gather 
Intraday do not chart in AMIBroker. QQQ and SPY are the two I would 
like to track minute by minute but the chart for both is blank. AMQuote 
doesn't have a problem gathering the data though.

Other symbols (like DIA) work fine.

Am I missing something?
