I checked your bot, and it is not connected to Twitter.
You need to go to your bot's Twitter page in its Admin Console and click on the "Connect" button. Do not click on Disconnect, as then your bot will not be connected.
To test your bot click on the "Check Status" button. You can its Log to check what it did and see any errors.
Not, on our main site, bots will only check their status once per day. You need to upgrade your account, or use our dedicated Twitter server to have your bot check its status more often.
