Hi all. I've read the other red light problems here and all the connection issues with the FSP. I just received mine today brand new, and right out of the box it's giving me trouble.

I'm using a bilingual 400-800 cable, Mac OS El Capitan all up to date. I did all the driver uninstall and reinstall methods. I changed my app security preferences. All the start up methods. Nothing. Solid red light all the time. Even when I completely unplug the cable, it doesn't even flash blue and red. It's still solid red. When I start it up, it does flash blue for a second and the input meter lights flash but then right back to solid red. I tried calling support but they're closed until Monday. Any suggestions or help? It's driving me insane because I just want to use this thing without sending it back.

I also tried it with an iMac I have running Mavericks, and I used the drivers for that OS, and it won't connect to it either. Solid red light when the cable is plugged in and even when no cable is attached.
