I've been working hard on this for 2 weeks and then when I saved it, it was fine but when I opened it again it now says invalid and won't open, I've tried EVERYTHING to fix this...I was using the Photoshop at my school since I don't have it for home....nothing worked....I really Need this back and fixed! Is there anyone who can try to fix it? I put the file on Mediafire with the link here. Somebody please help, I can't let this go.

ShadowExplorer.com - Downloads
I've looked at the file and can't open it.
