Connecting to the Plan G flight plan

[gredes]

Hi i am just setting up Plan G and saved my first flight plan.(In Plg format) How do I activate the saved flight plan. I set out and figured out that the radio stack activated the one in the Cessna. But it didn't follow the flight path and the waypoints. I could change the headings etc and tried clicking on the GPS button but it didn't follow the saved flight path.I have 2 monitors and saw some thing about issues with that does that have any bearing on this.
What am I missing here.

I always use MSFS > Flight Planner > Load button to load my saved flight plan in Plan-G. I use FS 9.
