had this perfectly plugin working on a previous computer. had to do a fresh install and is no longer shows up in OBS. noticed that in the 2.1.1 install instructions that it mentions the .ini , .json. and .data files. These files don't exist in the Zip file in the data folder.
In particular you will need to remove the old plugin files as noted in the instructions and then copy the unzipped new version of the plugin to the following folder on Windows (I'm assuming you're using Windows):
`C:\ProgramData\obs-studio\plugins`
If that folder doesn't already exist in ProgramData then you need to create the `obs-studio\plugins` folder. If you then copy the unzipped plugin there it should hopefully work.
