Sure, we'll try our best but without seeing the code all we can do is guess and speculate which isn't very efficient and usually not very effective.
But...since Wilsons problem was that he was compiling for the wrong device perhaps that's the issue you're having as well. If the code was originally written for 16F87 make sure you have that exact device selected in the dropdown of MicroCodeStudio (if that's what you're using).
