I bought my GE Expansion through the website

Unfortunately, we discovered that mixing CS store Expansions and Marketplace Livery Packs causes conflict between the two.
This means the "767-300ER GE Expansion" "777-300 PW Expansion" "777-300 RR Expansion" will not work with Marketplace Livery Packs.
We recommend to stick with either CS store or Marketplace products depending where you bought which expansion.
