Its not working from here in the UK. Edit: then I tried it again literally 20 seconds later and it is working, lol.
It seems that occasionally the LINDA website is unavailable so these links can be used as a backup. They are located in my own private Dropbox.
Linda V1.1 zip 5Mb - full package with all addon aircraft modules.
LINDA-v1.11_without_modules.zip (zip, 5Mb) - complete LINDA without any addon modules (but of course standard FSX aircraft).
LINDA Manual (PDF) -- read here on the installation process.
Brian's beginner Guide: "Indroducing LINDA" -- New users should really read this first before using LINDA, it has all the information you are ever likely to need.
