[GRASS-user] Error when using r.viewshed.cva

GRASS GRASS user

Good day,
When trying to run r.viewshed.cva i keep getting this error (see below) (This is the entire report, you can see the inputs).
Am I missing something obvious? I do not use Grass often, work mostly on ArcGis but I am moving towards Grass.

r.viewshed.cva input=Clip_haedarlikan@RHIVidsyni vector=Grass_vidsyniPrufa@RHIVidsyni output=prufa
Note that the routine is constrained to points in the current geographic region.

Oh, yes I forgot to mention that I’m not sure if the error is because of a lack of space or if the files are named in the wrong way. I suppose space is the problem, i thought I had moved everything to a location with enough space. Maybe I didn’t move the right directory.
