auto update for the new build couldn't write any files. SHur down HM2 and restarted and it still failed, shutdown machine and restarted and it failed again.

Also on a side note , each time it downloaded the update file each time. Could it be made so that updates are downloaded to an update folder, then when an update is detected , the update folder is checked to see if the update has already been downloaded. checksums could be used to check that the update file didn't get corruted during the download.
