How to attend live training sessions?

Sir I have registered for the course STAAD pro Advanced Analysis Engine,having registration order ID 199272. I was also been confirmed for the course via email but sir I could not find the join link for the class so that I can attend the class on time. I am suppose to attend the class on 8-09-2016 at 8:30 IST as mentioned to me via email.

Hence as I am going to attend the live training sessions for the first time I failed to understand the actual procedure how to attend live trainings so please guide me for the same at the earliest as the training is about to be held tonight.
