I was working on an important project. And than my cs3 said “another program is interfering with
Photoshop, program will now close” and now all the work is gone and the mane photo I was working off of isn’t in any known format. It wont open even when I try to run it with cs3 or any of my other design programs. Is their anyway to get the photo back or even get the hole project back.

I really need help on this, BIG TIME PLEASE !

Thank you sooooo very much

check the extension of the file(eg: .jpg, .tiff) maybe it lost its extension or worse got corrupted wich in anyway is very uncomun to photoshop
