No Sound after Installing BIAS FX2

[mark 3]

I know this is a common problem but there aren't any answers.

After doing everything PG says to do when installing I still get no sound out of BFX2.

I'm on Windows 10 64bit using Focusrite Scarlett DAW.

I can see the Scarlett is registering the input from my guitar.

Also when I use the test output option in BFX audio settings I get a tone.
I've installed ASIO, checked my settings in Windows to use it, basically everything I can think of but I still get nothing out of BFX

The volume levels in the BFX app show nothing.

So somewhere nothing is getting thru.

Probably a simple fix if you know what the problem is, but if you don't it's a real pissof.

Anyone know how to fix this?

Thanks
