Hello all!I don't know if I post this in the right forum, but I have a problem with my PMDG 747-400 wich I just bought from the shop.Loading goes without problems and I can use all the displays and buttons and displays in the cockpit, but after about one minute all the displays (except the CDU) go blank (black) and will remain like this whatever I do.Help! This package was to expensive for 50 seconds of fun!I've installed the latest drivers for my videocard.Best regards,Christiaan

Christiaan,that's a validation issue.You need to reinstall (uninstall/install) and register the product with an active internet connection.CheersThomas

Thank you! I'm going to try that now, although I've installed everything with the registration keys and stuff.Hasta logolight,Chrs

Hi Thomas,I've reinstalled the whole package (cd-version) and it seems to have solved my problem.Thank you very much!Regards,Christiaan

You're welcome.And...thank you for posting that it worked. You know, there are so many threads where people get advices and you never get a feedback if it worked or not. And that makes the search function a bit useless sometimes.So, greetings from Austria to Holland (right?)CheersThomas
