title: running pronterface in python: import error: no module named
body: <p>I am a complete beginner to programming, python, pronterface and 3d printing so unsurprisingly I am having a few difficulties.</p>
  
  <p>I have now managed to download pronterface and get it running on my computer, i think i followed the download instructions correctly and have skeinforge downloaded also in the printrun folder.</p>
  
  <p>My problem is that when I try to open or load a .stl file I get the following:</p>
  
  <pre><code>Skeining C:\Users\James\Downloads\70mm_Faberdashery_Yoda-Lite_less_robe.stl
  Skeinforge execution failed.
  Traceback (most recent call last):
    File "C:\Users\James\Desktop\3d printer software\pronterface\Printrun-d482c66\pronterface.py", line 940, in skein_func
      from skeinforge.skeinforge_application.skeinforge_utilities import skeinforge_craft
  ImportError: No module named skeinforge_application.skeinforge_utilities
  </code></pre>
  
  <p>However the file is in the right place I think:</p>
  
  <pre><code>C:\Users\James\Desktop\3dp\pronterface\Printrun-d482c66\skeinforge\skeinforge application\skeinforge utilities\skeinforge_craft
  </code></pre>
  
  <p>Can you try to explain in plain language any ideas to fix this as I am a total beginner and don't even really know what a module import error is.</p>
