HELP? PS won't open BMP

[+Josh Fx]

heyy there gfxvoid

I have been working on a magazine cover lately for a school assignment.

I have been saving it regularly but for some reason I can't open it now as a .psd!

I can't edit or do anything now. this is the message that comes up



please tell me how to fix? I've been using the same PS the whole time


Edit: I meant psd not bmp in the titled


Edit: ok I had an older version to use and I'm up to date now. this can be deleted now
