I recently updated to ArcMap 10.5.1 and I am trying to run a simple Extract by Mask tool that extracted a piece of a grid raster using a circular Shape file. I get an error that leads nowhere. I seems like I've overlooked some setting. I do have the Spatial Analyst extension selected. I figured that's all one needed. I've attached a screen shot of the output of running the tool. Does anyone have any idea of what I need to do?
