CTD on exit from FS2004.

Hi guys,First of all, let me say that the product is great.I have a strange problem. When I exit FS2004 by using any NON-PMDG plane like LDS767 prior to exit, I have standart message error "You have to restart FS9 due to....pmdgoptions.dll".When I use PMDG747 prior to exit from the sim, I don't have such type of message. I removed all PMDG stuff like 737NG and 747 and did full re-install for PMDG747 only. Nevertheless, while using any NON-PMDG plane. the problem with error message on exit from FS9 still exists.Best Regards,Dmitriy Toropov
