Hi Dan,

Have you installed all the software required for this tutorial? 

I followed these videos and steps and it works fine.

Instructions for Installing Ladybug + Honeybee:

(Follow steps 0-4 for basic functionality and 0-9 for full functionality)

0. If you have an old version of LB+HB, download the file here (https://app.box.com/s/ds96em9l6stxpcw8kgtf)

and open it in Grasshopper to remove your old Ladybug and Honeybee version.

1. Make sure that you have a working copy of both Rhino and Grasshopper installed.

2. Open Rhino and type "Grasshopper" into the command line (without quotations). Wait for grasshopper to load.

3. Install GHPython 0.6.0.3 by downloading the file at this link (http://www.food4rhino.com/project/ghpython?ufh) and

drag the .gha file onto the Grasshopper canvas.

4. Select and drag all of the userObject files (downloaded with this instructions file) onto your Grasshopper canvas.

You should see Ladybug and Honeybee appear as tabs on the grasshopper tool bar.

(If you are reading this instruction on github you can download them from http://www.food4rhino.com/project/ladybug-honeybee)

5. Restart Rhino and Grasshopper. You now have a fully-functioning Ladybug. For Honeybee, continue to the following:

6. Install Radiance to C:\Radiance by downloading it from this link
(https://github.com/NREL/Radiance/releases/download/4.2.2/radiance-4...) and running the exe.

7. Install Daysim 4.0 for Windows to C:\DAYSIM by downloading it at this link (http://daysim.ning.com/page/download) and running the exe.

8. Install EnergyPlus 8.1 to C:\EnergyPlusV8-1-0 by going to the DOE website
(http://apps1.eere.energy.gov/buildings/energyplus/energyplus_downlo...), making an account, going to "download older

versions of EnergyPlus, selecting 8.1 and running the exe.

9. Copy falsecolor2.exe (http://pyrat.googlecode.com/files/falsecolor2.exe) and evalglare.exe
(http://www.ise.fraunhofer.de/en/downloads-englisch/software/evalgla...) to C:\Radiance\bin

10. You now have a fully-working version of Ladybug + Honeybee. Get started visualizing weather data with these video tutorials
(https://www.youtube.com/playlist?list=PLruLh1AdY-Sj_XGz3kzHUoWmpWDX...).

After I've done all the above I followed this video 

https://vimeo.com/96155674

And everything works well.
