Pin sprite to player in 'Space Blaster' example

I'm a C2 noob, apologies

Using the 'Space Blaster' example, I'm just trying to pin a sprite to the player, using rope physics. My setup (following other examples) works with other sample games, but it doesn't seem to work with 'Space Blaster'.

Is there some reason for this: maybe 'Space Blaster' is setup differently? Thank you! <img src="smileys/smiley2.gif" border="0" align="middle" />
