I was recently working on a file for hours and kept putting off saving for some reason, big mistake! Save Often! I am working in 5.3 with SX10 scan data. I have 8 scans in the drawing and was cleaning up the regions moving items from the default layer and so on. The processing overtime was getting slower I could tell but I kept working along. THEN AN ERROR POPPED UP. It said to save the file, close it, and reopen it. I noticed that a few of my regions disappeared instantly before it crashed. I saved the file as the instructions told me to and closed the program. I reopened the file and I am still missing the data from three of the regions that were open at the time. Is there anything I can do besides start over? The two regions that I was actually working on adding data to are still ok and in the file. It was the background regions that disappeared? I am not sure what files if any you might need to review? I am also leaving on vacation for a week so if I don't respond it's not that I don't care I may not have access.
