Once you have the plugin installed you will be redirected to a page and prompted to enter your email address. Once you submit your email address you will be sent an email and ask to click on an account activation link. Once you click on this link you will be brought back to the Proxmate site and will be able to start viewing channels.
You are not required to enter a password as all of your account information is displayed in the plugin.
Please note that if you uninstall the plugin at any stage and reinstall it you will be asked to enter your email address and sent another link to activate your account. All you need to do is enter the email address that you initially used to sign up.
