Crazyscan with Nova HD S2

I had a look at the other threads around the site so hope i'm not duplicating anything.

I have a Nova HD S2 and am trying to use crazyscan with it.

XP32
crazyscan 1.0.1.94
extracted reqlibs into the same folder.
using StreamReaderEx for BDA Tuners 1.1.0.1162 downloaded from here.

Upon startup it now says "RFScan not supported"
Is my card supported?
Is there anything I am doing wrong, do I need to put the crazycan folder in a specific place?
