I've just installed BIAB on my new Windows 8.1 laptop and the Real Tracks are not working.

"Real Drums not found" and "Real Tracks not found" are the messages that I get in the message box at the bottom right of the window.

In the Style Picker many styles are on a grey background. They play the demo track but if I select them for my tune I get the 'not found' error message.

Any ideas what I have done incorrectly or a setting I have missed? I didn't have this problem when I installed on my previous Windows 7 machine.

I'm on BIAB Version 2014 (381)

Thanks in advance.
