make sure there are no spaces in your project's folder.

if you changed the name of a texture or sprite and efpse is looking for it, you will get errors like this also.

you can open your textures.dat file, and manually compare it to all the textures in your /Textures folder, make sure you didn't rename anything

it is definately an issue with filename tho, you musta renamed a file or you renamed your project folder or something.

Or maybe you created a project NOT inside the Projects folder.
