Some ideas:

.Use v.info on your map and see how many areas are reported? Maybe you
need to run v.clean to check for broken polygons (?).

.Be sure that your boundary is closed. You will have to "close" it

.Add a centroid and "Save & Exit"

.In your GIS-Manager uncheck all except area to see whether you have
area(s) or not
