PCX is not TGAI had this and had to scrap it and start again - the editor was looking for a non-existant PCX file when I always use TGA for textures.
I think the project file may be corrupted in some way - but I'm only guessing
I haven't been able to sort iy out 
I always save as I go and use a serialised save-
Mylevel-01
Mylevel-02
etc
that way, when 'it' inevitably hits the fan and everything goes South I don't lose too much work.
I hope you get it fixed - I couldn't
Save soon, save often is my motto
