It has come to our attention that the program called "Console" from UAD will grab your MIDI devices on a Windows machine and not allow them to work in any DAW. The ports for your Faderport 8 will show up in your DAW, but the "send to" ports will not work. They will fail silently. If you are using a UAD device and you have "Console" installed, you will want to open Console in your startup tray and go into your Console Settings>MIDI panel and disable the Faderport 8. Once you have set the device value to "none," you should be able to use the device in your DAW.
Here is a link to this information on UAD's web site.
