It looks like our app was unable to check for updates for a long period of time. This can be because of no activity from your side or you (or your firewall or antivirus) blocked internet connection for our app.
Please be advised, that after a while our app will stop working if it will not be able to check for updates.
If you see this message too often, please contact us. Or at least try to let our app connect to the internet to check for updates (unblock it in firewall and antivirus).
