I have installed many add-ons, and I'm pretty much 100% sure I've uploaded the files correctly; as they are just like any other addon files, with the same method. Yet, no matter how many times I try, or even start over from scratch and try, I run into this issue.
"Error - The files associated with this add-on could not be found. Please upload them and try again."
Which, trust me, I have done many times.
Perhaps the last update may have messed it up for new people trying to install the addon?
I've never had this add-on before, so I didn't go through the update process.
