Oh brother! I'm real sorry, guys... Can somebody push me in the right direction, please?

I've read post after post after post on this 'till my eyes are popping out.
Edited and removed screenshots:
Figured it out. In "Settings" I added ticks to "Lago MD80 Maddog" and "FSX GPS", created a folder named "Lago/Maddog/Routes" in FSX root, and voila! - the plans appeared.
I also noted from another post this reference:
"Hi, I´ve bought the FSBUILD2.3 today, upgraded on the newest version 2.3.7..,"
Mine shows 2.3.1, build 209. Are there other upgrades - other than that on SimMarket?
Please tell me... I can't be this dumb?
