We were able to download the new Aviation Design Kit but we were unable to open it. When we tried opening it, it says it's empty or source file cannot be read. Is anyone else having this problem?
Are you trying to open a particular file when you get that error; or are you just trying to open the downloaded zip folder?
I was able to download the zip file and extract it without problem.
We found our problem: our network firewalls were blocking the file making us unable to successfully download it.
