Livery Manager Root Directory

I got the NGX maybe a month ago.  I just recently tried to add more liveries to FSX.  I downloaded them from the PMDG website and started the Livery Manager.

I am unable to get the Livery Manager to recognize the FSX root folder.  I run two hard drives on my computer.  I have a small SSD which has windows and not much else as my C drive.  The majority of my files, including FSX, are run off of my much larger HDD on the E Drive.  I'm guessing my problem must has something to do with dual hard drives but I'm sure I can't be the only PMDG user to have this kind of setup.  Regardless, I can't get the Livery Manager to recognize I have the NGX on the computer.

And Yes, I did purchase the NGX and install it legitimately.  :wink:

Does anyone have any tips or suggestions?
