I seem to be stuck on WEB UI page. I have downloaded launcher client and installed the files for x-plane. When I filed my flight plan (VFR) it launched x-plane and then I'm stuck on the WEB UI screen. Not able to get my sqwak code to start the flight. What might I be doing wrong?

Thanks

You need to make sure that your departure time is within 35 minutes. Once you spawn on the ground and are connected online, open the WEB UI and go to ATC -> LOGON. On this page enter the 4 letter FIR you are in, for USA enter KUSA. Then enter your callsign you filed and press the SEND button. 
 

You will receive your squawk code after a few second of doing this. Once you do, takeoff to activate your flight plan. 

Still have not been able to get the WEB UI to work. The buttons are not  clickable,  just boxes and Im not able to go to ATC and logon .  I am online based on the dashboard showing the option to log out. I've filed three flight plans and have yet been able to get up and complete the flights. Is there a specific sequence I need to be following to launch Poscon and then the sim? Or am I just not getting it? Im really trying to figure this out, but the steps Ive taken have not worked yet. Thanks for the help.

Under X-Plane itself, the Plugins menu, go to POSCON and log onto the network.
