Ive just downloaded the windows wallet but it says "no block source available" ??

Hi - I downloaded the wallet however this PC is using Windows version 10 - so I've tried the one for Windows 7/8 but I also get no block source available.  Checked firewalls and left it overnight already but no change in the morning. Any thoughts?

Hey how do i get the wallet in sync right now its saying (out of sync) and no block source available.
I did nothing but opened it normally in past experiences i remember it just getting synced up by itself.
