installer download stops at 42% for InDesign, Illustrator and Photoshop. Even after 5 hours, still nothing...

I've been trying for a while but my installation never could be completed. All of the updates get stuck at 42%.

The only update that finished was 'Scout CC', i don't even need it but i tested this one because i thought it was not that heacy.

So, it did work, so nothing is wrong with my account/membership.

I'm using an iMac with OS X 10.10.5
