Try to reinstall your 747 and don't modify any files before you install the LCF. Additionally, please obey the forum rules unless you want this thread deleted. If you are reluctant to disclose your name, open a ticket with PMDG support. Visit the website for more information and have your order details ready.

Hi Linde, Forum rules are actually for "Full" name (first and last) and required in all our posts, thanks.Your problem sounds like the same as this post linked below.
