EB 1.6.9: Undefined index router.php

I put in a Support Ticket as well - but we're trying to launch our newly designed website and using the very latest version of Events Booking but getting this error when we click the Register Button:

Notice: Undefined index: id in /components/com_eventbooking/router.php on line 47

Can anyone help?

See your ticket. Maybe you should upgrade to 1.6.10 and check it again first ? It is 8:40pm here now, so I can only check it on tomorrow morning. There are still too many things left for tonight here, please wait for me

Sorry my mistake I am using: Event Booking version 1.6.10
Please check it tomorrow.
I have set display errors in Global Configuration to "No" for now.
thank you!

OK Kathy. Seems I don't see your ticket. Will look at it abit later today
