Application manager failed to update error A12E1

I signed up for the Creative Cloud Photography package (Lightroom and PS) about a week ago and today it informed me it required an update. So i clicked on update, as you do? After a while the afore mentioned error code popped up.

After several failed retries, on both my laoptop and desktop pcs running windows 8.1 and 7 respectively, both 64 bit, I decided to uninstall and try restarting from scratch. So i uninstalled the Aplication manager from Control Panel.

Now it wont even reinstall on either PC, i get the little grey window pop up with the green bar that goes across and that is it??

Where do i go from here? I have only had it a week and its broke, cant say i am overly impressed with CC to be honest, it wasn't exactly straight forward to get PS etc installed in the first place and now this.
