Nah, I was putting pictures to music. Was using transitions and effects between/over pictures and it all of a sudden came up with dialogue saying the there was some error and the program had to close. It was model, so I could not do anything but say ok. I just did not save, I usually do, but got carried away and lost all my work. I was only using normal picture file (Jpg, png and and Gif).
Was praying for some kind of recovery of at least some of it, but no such luck :(
