Hi Guys!I'm new in pmdg 747 also i've installed the 737. But since i've installed the 747 I have a bug that I don't know if is related with the pmdg 747, with my graphic card or even is not a bug!the problem is:I start the FS2004 and I create a flight with the pmdg 747. When all is loaded, in the 2D or 3D view I see the PFD and ND working fine but, a minute later all this screens become black and I can't turn on. Is it normal? or is some bug related to something?I've a ati radeon 256MB 9550 AGP X8, pentium 4 at 2.4Ghz.thanks in advanced!

That's a validation issue. You need to revalidate your product.Also, you need to sign your posts with your real name. PMDG forum rules.

Nameless-I just ran your IP address through the validation logs to see if I could locate your account in order to help you....I don't find anything, however.The problem you are seeing is related to an improperly validated installation, and/or a correctly validated installation that has been altered, thus tripping the fraud protection....Give us a bit more information on your installation and I'm sure we can help you get back up and running...
