I have been trying to upgrade all of my computers to Win 8.1. 2 updated fine, but the last machine will not upgrade. Every time I try to upgrade my last computer through the Store I get the following error: "We weren't able to connect to the Store. This might have happened because of a server problem or the network connection might have timed out. Please wait a few minutes and Try Again." I have waited, and rebooted, with no success. I tried to log on using my Windows Live ID and get a similar message. Any Suggestions??
