If you see the error “Initialization failed. Please relaunch CMS” when click on the Peer-to-Peer module button, it is probable that your platform’s password has expired and should be updated.
When you first log in, if you see a page saying “Password Expired. Your password has expired, please create a new one before continuing.”, then ensure you do update your password. Once you log off and back on, the Peer-to-Peer module should start working correctly.
