I received the update notification for Beta 2. I go to update and the download just seems to hang. I got down to 15 minutes left and it went for a few hours without completing. I rebooted and attempted the install again and now the update still shows as available but when i go to update it, nothing happens. I get the downloading message but no indication or progress. I let it run overnight just to see if it would eventually complete but it didn't. Is there something on the system that i need to clean up?
