REST doesn't support the selected ROI definition now

Hi

I am hoping to get help with a difficulty that I'm having whilst running restplus. It was at the following step that the run terminated. I had uploaded a nii.gz file as ROI demarcating a region of the ventral default mode network sourced from the findlab (http://findlab.stanford.edu/functional_ROIs.html). 

I've not been able to figure out where I've gone wrong. Your advice would be very much appreciated.
