CC works fine on the Mac laptop but doesn't download to the PC desktop

Strange. It works fine on the laptop (Mac, OSX Mavericks) but doesn't download on the PC desktop (Windows 7) I also have upstairs.  The CC Install App downloads, but whenever I click 'download' on the CC Website nothing happens, no progress bar--no nothin'!  Any ideas? I've tried msConfig and disabled non-essentials and rebooted, disconnected the router and hard-wired it in the event the firewall was blocking the data (I didn't wanna mess with port forwarding).  I'm at a loss here gang. I am a student and use After Effects, Illustrator and Photoshop regularly and need to have the access when my brother uses the laptop!

Thanks for listening,

Matt
