Hi Ricky123
I'm not with Laminar Research, just a fellow simmer in the UK, but could you please advise the following:-
1. What is the name of the Seattle scenery file and where did you purchase it from?
2. Is the Seattle scenery file listed in the X-Plane 11\Custom Scenery Folder? Please click on the following link to show you how to find this:-

3. Can you please upload a copy of the X-Plane 11\Customer Scenery\scenery_packs.ini file, as shown on the above link?
If your not sure how to do this, please let me know and I will send you further instructions?
Regards
