April 14, 201610 yr Hi all, I have bought the PMDG 737 NGX base pack and the expansion. Both are SP1D. When I have installed the expansion package it asks for a serial, I put my serial and then it says: succesfully activated. When I click at fly now by FSX, the expansion pack works for 20-30 seconds and then it freezes, screens aren't black, but it freezes completely. The base package works good, no any freezes. I have the PMDG 737 base pack boxed version of Aerosoft and the PMDG 737 expansion is a download of Aersoft, not from the PMDG Ecommence. Could anybody help me, please? Thanks for your help and support! Yours faithfully, Koray (Kd555)
