Why has Preview just sabotaged a whole weeks worth of work?!?!
Okay so I am an illustrator and I work with photoshop, last night I opened one of my pieces that I have been working on non stop for the past week in Preview... This morning I realized that was a HUGE mistake, it has ruined my .psd file by merging all layers into one, as you can probably guess I am extrememly frustrated by this and what is more frustrating is there was no warning message that this would happen! Please, is there a way to get my original .psd file back?!?!?!
URGENT!
