okay...something very weird happening.
The download link didn't work for me either.
You are correct, the Assembly sheet link doesn't work (mediafire shows me an error screen).
So I went to mediafire and looked through the files and couldn't find the PDF for ECTO 1 assembly anywhere.
It just wasn't there.
I don't know where its gone, but its gone.
So I uploaded a new copy of it...and...POOF...there it was!
I recognized it immediately because the new one I just uploaded had a slightly different file name.
So now there's two of them up there!
The original PDF just reappeared! along with the one I just uploaded.
So I came back here, and clicked the download link again, and now it works!
I haven't changed anything yet, but it works again.
I checked the download again, it works no problem.
The interwebs is a screwy place.
Can you guys try it?...
if need be, I'll update it to the new file I just uploaded, but...if it works...
