I have recently bought PMDG 777 and updated my simulator to FSX. I have few problems if you can help. I got your email from AVSIM forum.
My issues are
I have activated product but still It ask again to activate it
I don't have active Operation centre.
I don't have all the documents except Tutorial and Introduction
Once I load I can't see the Cockpit except a bit of EFIS and a bit of PFD&ND on captain and FO side.
