PNG from inkscape invisible in Fengrave

I cant see the image when I load it into Fengrave

Same goes if I export this to a PNG, it is like it comes out blank. I must have changed a setting somewhere but cant find it.

I had this happen to me once and it was the result of transparency (alpha channel) I killed the alpha channel (in this case I think I converted it to a JPG) and it worked.
