AutoCAD Inventor :: Not Rendering Simple Sketch

I have downloaded Inventor 14, and the program appears to start up without problems.  However, when i create a simple sketch, it first says "Choose a plane".  In my textbook, it shows a picture of the three planes to choose from.  However, my computer screen shows a blank gray screen.  It appears some tool bars are missing as well.

However, if i click in the space where I imagine the axis should be, it takes me into sketch mode. Similarly, when I draw a line, the information bar reads like I am drawing a line, but no line shows up on the screen.

Is there a specific requirement on my computer I could be missing?  I have downloaded Inventor twice, and both times had the same problem with the program.  Perhaps a video card I need to have, or a certain RAM requirement?
