Historical data error 162 No queries

[jehill parikh]

Hi All, 

I was previously able to download historical data using demo login a couple of months back, however, now I get the following error 

Server Error: <error id=0, errorCode=162, errorMsg=Historical Market Data Service error message:No queries>

I am aware of the parsing restrictions have factored them in my code. Before doing major debugging, I thought to check if anyone on the forum knows about this error (especially the "No queries") aspect. I can't find any information on that. 

I have checked on two separate installs, re-connection etc, wonder if there is anything changed recently ?

Many thanks and regards

Jehill
