C++ compiling

I know im a newb, im having a hard time figuring out programming by myself.. Heres my situation. I downloaded a simple MP3 program for my computer, and i also downloaded the source with it. I wanted to have a little fun, and took a whack a mole at changing little things.

so i opened the source code, and changed the back ground skin in photoshop. now, i cant seem to compile the over all entire program. im using bloodshed as a compiler. thanks in advanced
