I applied for a trial demo and it is saying I already had one?

CQG and Rithmic data trials are only available for one-time use since the data feed is not free.

CQG, for example, works with many platforms across the entire futures industry. If you are receiving a message stating that you have "Exceeded your demo usage," this typically means the email address you used to register the demo was most likely used in the past for another trading platform, which, as a result, will generate this message. 

Most trading platforms will provide a permanent simulation mode typically built within the software. You can open an account with a $100 minimum balance and pay the relevant data fees. You can access LIVE connections and a permanent, non-expiring demo if the trading platform supports "Local Simulation mode."

Here are the data fees for reference - https://www.ampfutures.com/trading-info/exchange-data-fees
