Putio Plex with v2 api
Forked from https://github.com/Logaritmisk modified it to work for Put.io api v2.
Download as zip file, extract Putio.bundle folder to plugins folder (somewhere like C:\Documents and Settings\Administrator\Local Settings\Application Data\Plex Media Server\Plug-ins)
Visit, http://put.io/v2/oauth2/apptoken/28 and enter the code in plex settings.
Enjoy.
