Got the GP Version last week but had difficulty remembering my password... sorted that today but I need help ASAP... like within the hour sort of speak before I got to Yas Marina Circuit

I've connected the Go pro 3+ to the laptimer with no issues... turn on the wifi to the gopro and go onto Laptimer and select the go pro... go pro turns on... Good...
However I can't get the video to come on? Should it come on? Do I record from the camera and the data will transfer?
Also for laps... it will automatically start at start finish line?
i'm like a dinosaur with this and leave it last minute haha.
