Hi,I purchased the 747 and had little issue's with the product at all BUT still decided to upload the latest patch after visting PDMG's website.Now I am having countless issue's .......... mostly thick black smoke from the four engines after initial load at the gate.This wasnt there before and wasnt even an issue for a couple of hours after uploading the latest patch .......I didnt change anything in the settings that I am aware of so I presume its got to be the patch ...... can anyone please help.I am using FSX & Vista ....Thanks a million P.S.Also was considering buying the FS crew add on for the 747 ..... anybody think it's worth the investment

Same problem here regarding the smoke. It's not repeatable though, perhaps every 10 or 15 flights it happens.

Seen it as well at random since SP2 and never discovered a fix since it cannot be replicated.

Known problem with FSX advanced animations, see this: http://ops.precisionmanuals.com/wiki/PMDG_...fails_to_reload

Guys ...Thanks, I think I was just extremely unlucky to have it happen to me twice in a row which had me thinking it was a persistent problem.I loaded up last night and the smoke had gone and the plane operated as good as ever ......... thank godRegardsJohnP.S.Still have no answer for FS2 Crew add on ..... Anybody using it and what
