It seems you requested too much historical data at once. Please check if you have workspaces running in the background that will also request data.

Please go to File-->Workspaces and check for workspaces in between "Save Workspace As" and "Default". Select each workspace one by one and close it via File-->Workspaces-->Close Workspace.

If you receive this error, please wait 5 minute and you should be able to request data again.
