Hi! I have bought 777-300 expansion. But whaen I tried to intsll it I saw this

 

What I need to do?

Update your 200 lr/f?

What does the dialog say?

It says you need a version or later, so maybe open PMDG operations center and check for update?

I updated base pack just minute ago and everything starts working! Thanks a lot

Glad you figured it out:)
