I understand that you've already fixed the issue but this is more to do about you issue with wanting Photoshop. There is a version of GIMP that acts more like PS if that's what your looking for. I think this is the [link] if your interested.
The layout is different so that it mimics PS. It's more for people that have experience using PS but may not have the means of getting the suite. You know, tools are laid out in a way similar to PS but the program is still just GIMP with a UI tweak.
