Just added the Command Line command to my v2 installation, followed the instructions in the text file verbatim, and now I'm getting the above error code any time I try to draw a rectangle. Doesn't matter what type I try to draw - corner, center or 3 pts. I draw out the rectangle and the error message appears when I try to complete the command (2nd left click). I dismiss the error message and the rectangle I just drew vanishes...

Is there something I can do to fix this that doesn't involve removing the CLine command?
