Oh, I see! In that case, you can go to the Settings Tab and General Settings. Then, go to the Remote tab. Here, you can adjust the Hardware/USB Remote drop-down list. Go through this list one by one, testing each time to see if it works properly. Once you find the one that works, you can leave it set that way and it should allow your Remote and your "PF" key to work properly!
Note: When testing, make sure you are looking at your Main Screen at the front of your Sanctuary. If you are looking at the Viewers or Editor within MediaShout, it can be a bit deceiving.
If you need some help with this, please give our Support Team a call. 866.857.1292
Thanks and God Bless,
