Download appears corrupted!

Signed upto the Creative Cloud for the year, no previous adobe software installed on this machine (windows 7)

I cant download any of the apps I want though..

I have read though all the threads on similar probs

     use clean up tool

    "Cannot open mediadb"  delete OOBE file

It has download Edge and Acrobat (so it works randomly) - 1 at a time once I preformed a clean up and reinstall.... but fails to download anything I select there-after "Download appears corrupted" messgage! I'm totaly frustarted with this now.

Shocking service, I have wasted well over 6 hours messing about with what should be a simple process.
