PIA (SOLVED)

Hi, I have the latest version of Ubuntu and I have Firefox as my browser.  I have an account with Private Internet Access (PIA) and what to install it on my desktop.  For some reason Firefox will not take me to any of their web pages, I just get "page not found", but I can access all other web pages.  So I cannot get the download from their site, I managed to get the PIA add on for Firefox, but when I connect to PIA, it just stops me connecting to the internet.  Any help would be very welcome.
