Data feed could not be loaded error message

There can be multiple reasons for the Data feed could not be loaded message.

• One of the data feeds that is used on your workspaces or in the QuoteManager is disabled in QuoteManager → Tools → Data sources.
  Close this chart or activate the data feed for it. Changing the data feed Status requires restart of all MultiCharts Processes for having the changes applied.
• During MultiCharts installation, not all of the data feed DLLs have been installed due to antivirus/firewall activity.
  Please close MultiCharts and all of its products. Make sure all processes are finished. Then go to the MultiCharts folder (make a right click on the MultiCharts shortcut → Properties → Shortcut tab → select Open file location) and run DataUpdater.exe
