Hi guys. I am new to FSX so plz bear with me. I havent added on too much so far. I have FSDT KJFK and KORD. A few planes pmdg J41, feelthere ERJ 2, DA Fokker 100. I loaded up at KJFK after installed the ERJ and the gates are there but the walkway up to the terminal is missing. Anyone give me an idea to remedy this problem? thx all!

Recommend you join the FSDT forum and look in the forum support posts there. The loss of airport buildings at FSDT airports has been a common happening, and is usually the result of the end-user doing something wrong during the installation and\or activation of the product. There are numerous posts there identifying the problem(s) and how to fix them.

You might need to set the scenery option higher. I forget what's called, but it's under Display -> Scenery and the options are things like Sparse, Very Sparse, Dense, and Very Dense.Then again, it might not apply to certain addon scenery
