Can't download from one site

Hi!
using the latest beta, I can't download from here https://www.textpad.com/file?path=v9/setupv9.exe

after filling in the CAPTCHA, nothing happens for about 20 seconds until AntDM notifies me that it received an HTML file instead. disabling antdm allows downloading with the browser normally.

well...?

edit: Damn, now it works.

I could not download this file even if I disable AntDM extension (firefox, chrome).
It's probably a problem with the site itself.

strangely enough, I tried again afater a day or two and it worked, even with antdm enabled
