Saving in Vue is crucial - its a bit finicky at times (in my experience) so you may have to go to the .bak file if you have one. Make certain all maintenance on the computer has been done (defrag, check disk etc.)recently and save often using different names IE RED_two.vue, RED_three.vue. Never save 1.vue, 2.vue etc. because for some reason vue doesn't get it at times (not sure why - saw it in a thread somewhere). Also check search for recovery and saving tips from other users.
