Does the black screen signify that there is an error with my code, or is there something wrong with the SED itself?
For sure not. Errors are signalized through error messages. Make sure you run the file you're editing by pressing alt + f5. You have to include acknex.h. And it's default.c not defualt.c. Dunnow if that's just a typo here or in your code.
Always learn from history, to be sure you make the same mistakes again...
