Just went and checked, both menus are visible, and I do not run any anti virus other than a manual scan with malwarebytes every so often.
I purchased this last night by downloading and installing the FS9 version and I completed the purchase in FS9 making it active in FS9. Then I installed it to FSX. I'll try reinstall and see if that works.
Edit - Nope that didn't work either.
Edit 2 - Fixed it. I had to download the addon manager again. When I buy a scenery I put the installers and reg backup in a folder in my external HD as a backup. I had the standalone manager there so I installed it and it didn't fix it. So I went and re-downloaded it and walla, it works! Great scenery, worth the money as always. Thanks
