Jekyll serve "Error: Invalid argument" issue

Question

I'm currently running through the stages of installing and generating a Jekyll site locally on my Windows 7 PC. I've installed all the requirements and can get Jekyll to initiate, but I can't get it to serve. Whenever I try it returns the following error:

    $ jekyll serve -t
