Why not able to download the Free 30-day Acrobat Pro?

Does anyone have experience with error messages when downloading the free 30-day Acrobat Pro? The download started as it should, but after 55% it stops with an error message (in Dutch):

"An error has occurred.

The Acrobat-installation program has discovered an unexpected error. Please try again. If the error remains, contact the support center of Adobe."

I tried a couple of times, restarted the Mac, closed the browser etc. but am out of options now.

Also tried to find the Support center, but this does not seem to exist....

I really hope someone here can help me.
