Oh, man, I had one that pissed me off so much. I worked on it for a long time, it was really cool. I was excited about showing it off and printing it out.
I don't know what I did, or if I just had gremlins or something, I though I saved it as a .psd but after I saved it and tried to open it again all I got was a message that 'the file is not compatible with this version of photoshop'.
Apparently the file is not 'compatible' with any art program. Any PROGRAM for that matter.
WTF. Still have the damn thing saved somewhere. In hopes that I will figure out a way to open it again.
E Yes I also tend to rip pages out of my sketchbook if I'm dissatisfied with the drawing. Looking back on that now I really wish I didn't because I had some really cool ideas. Can't change the past I guess.
