Error code 0xc004f015

I upgraded to windows 10 online during the free upgrade period. Computer has been crashing ever since, won't update or activate and gives the error code 0xc004f015 at the 95% completed mark when I attempt an update. If I use the "activate windows" button
in the main control panel area it tells me i'm not connected to the internet, which is incorrect. Any help would be appreciated as we haven't updated our system since installing windows 10 over a year ago. Thank you.
