file damaged if downloaded via download manager

Hi, I have had a couple of files on download manager for awhile and they work great.

I just added a new today and when I downloaded it I got an error the the file is damaged and cannot be repaired. Here’s the link:

But if I go to the URL directly to download it, it downloads with no error. Same file. Here’s the link:

Just a couple of notes (not sure if they matter):
– the files that are already in download manager that work are larger files (ruled out file size)
– I tried both adding the file from my computer and adding the file from the server
– I am using a mac, but the download error also happens on pc.
– I can open the file on my mac fine. I upload via ftp, add it to download manager, download and get error.

Thank you very much for your help!!

I solved the problem – sort of. I removed some security I had set for copying and printing the file (not opening). Once I removed those security settings everything worked. I would still like it to work with those security settings on if there is an answer but for now I have a work-around. Thanks!

Ok, thanks for letting me know Shaon.
