Just did (or was trying anyway) to do a render that takes at least 8 hours.  Started it went to bed and when I checked to see the master piece (my opinion here ) :)  I discovered that windows had decided to update and rebooted the computer. @#$%#  lost all that data and time!  Yes I have a back up but I still had made tweeks and changes to the master which have to be made again.

Yeah I know this is Windows deal, but it screwed with my VUE!!!!!!!
