You have a whole year after the 29th to take advantage of the free upgrade offer. All depends on your definition or "now" I guess.
I believe this issue is related to the recent update that's causing explorer.exe crashes and other issues for many people.
Gabe Aul has said on Twitter that a fix is coming.

Not all systems are being affected in the same way, but I believe that the network setting issue is related to this. I'll try to uninstall that update later and try again.
I could not open the control panel so I am back on 7 until at least the 29th.
