.pmd importer/exporter not working

I don’t know if anyone else has had this problem trying to install either of these plug-ins, but whenever I try to install either of these, I get an indication that it’s installed, but they don’t show up in the user preferences module. I’m not sure why this is happening, either. (I’m using 2.77, in case anyone’s wondering)

These are the two add-ons I’ve been trying to import (highlighted in yellow):

The notification I get is “add-on installed from [folder I placed them in on external HD] to [C:\Users\Owner\AppData\Roaming\Blender Foundation\Blender\2.77\scripts\addons]”. So again, I can’t say for sure why the addons aren’t showing up in the user preferences.

py meshio requires some more effort to install. but it’s not running correct.
mmd tools works great.
xna also works great :wink:

other issue you may have is the folder names might need to be remove the -master
