I'm sorry that your post didn't receive an answer yet. Perhaps your problem has been solved, in that case it would be nice if you would mention it here.
If it's not solved, some hints: if you want to include postscript files, use the eps format instead of ps. Use latex, not pdflatex. If the figure doesn't appear it could be caused by a draft option. Omit spaces in file names and paths.
In general you would get more specific help if you post the error message or provide enough of your code.
