Troubleshooting for Photoshop: 

1) Please make sure you are loading the ".abr" brush file. This is the
brush file that the Photoshop brush engine accepts. Please do not
try to load the .brushfile files into Photoshop.

2) I have heard this set does work in CS6, but it does not work in
CS5 and below. It was created for CC, so there may be differences
between the CS6 set and the CC set. I don't have access to CS6 so I
am not sure. Feel free to delete any brushes that don't work 
properly in CS6.

3) To load them into Photoshop CC, Use the gear icon at the top right corner
of the brush presets panel, and click "import brushes". Now select 
the .abr brush file.

4) To adjust any of the settings to your liking, open up the brush settings panel
from under the "Window" dropdown menu. Make whatever adjustments you need, and
then click the plus box at the bottom to save this new brush with the 
adjusted settings. Now drag that brush to whatever placement you wish in 
your brush organization, it will appear at the very bottom of all your
brushes.

4a) To remove the color jitter, please uncheck the "Color Dynamics" box.

5) If you are still having a problem and cannot figure out a solution, 
please email me at devinellekurtz@gmail.com with screenshots of your
problem. Please let me know that you have run through the steps
above. I will do my best to help as many people as I can but cannot
guarantee I will be able to help everyone individually as there have
been over 20k downloads. Reddit and twitter are excellent places to
get help with brushes.

Troubleshooting for Procreate:

1) Please make sure you're loading the .brushfile files. The .abr file
will be missing a lot of adjustments.

2) Please try loading them directly from your file storage or from Dropbox/Google Drive.

3) Please try moving them into a different storage area and trying again if you
have problems.
