How to get Esignal symbols active?

Hi everyone,
I've subscribed to Esignal, and installed the eSignal Data Manager, and configured as instructions. The connection status is green OK. But I can't see any symbols in the list as the enclosed image.

What should I do to fix this. Thank you very much.

After subscribing to Esignal and installing the eSignal Data Manager, you need to add symbols to your database in order to see them in the list. To add symbols, go to Symbol -> New menu and enter one or more tickers (comma separated) you wish to add to your database. Once you have added the symbols, you may need to wait a few seconds (depending on the speed of your internet connection) to backfill historical data.
