Sigh. Have done this more times than I can count and can commiserate, hun. And papers. And elements. And doodles. And previews for products. Hahaha...but ugh, seriously ugh.
Blurgh! That is no fun at all! But... you're in good company here. I think we've all done that at some point. We feel your pain!
I am notorious for not saving my pages. My issue is that I am lazy and I don't save as I go. I use PSE 6 and just last night when crash plan was backing up and I was trying to open something, it took forever and I seriously thought it was going to crash. The dreaded adobe is not responding message came up. Luckily for me, it didn't crash and I was able to finally save my page. I totally sympathize with you. I am really trying to remember to save as I go, but I just don't do it.
