Reinstalled OS, now Reaper won't play

[DeadlySurfer]

Hey,

So I'm running Windows 7 Pro, 64 bit. My interface is a Focusrite 18i8 Gen 1.

Basically I had this set up and everything was fine, but I had to reinstall my OS. Reaper now will sometimes playback and record, but mostly I'll hit play and it will say 'Playing', but there's no movement on the track.

I've reinstalled the interface drivers, changed the power options for my PC, everything I can think of. Using Direct Sound works, so it does seem to be an issue with the interface.

Thanks in advance!

I assume when you go look in Prefs/options/Audio/Device/ in Reaper your focusrite is showing up as it is supposed to?

Yeah, it's showing up as I'd expect. Shows I can select all the ins and outs, just like before reinstalling the OS.
