Cavity mapping problem help needed.

Im working on a model at the moment and have come to the point where I want to start exporting out my maps. Ive already got my displacement map but when it comes to the cavity map all I seem to keep getting is pure black with white dots (see below). This also seems to happen with the AO map.

Ive used the multi map exported before and I had no problem however it seems I may have changed a setting by mistake as something is definitely not right. Ive tried resetting the presets but to no avail. Its probably something really obvious but Im stumped!
Any help would be really appreciated.
