You may have to do the following:
CollisionOff(e)
ResetRotation(e, 0, Y-angle, 0 )
CollisionOn(e)
Don't know why exactly but if you don't it may not move at all!
Y-angle should be -180 to +180 btw but if all you want is for it to face away from you just use the player Y angle. (i.e. g_PlayerAngY)
Been there, done that, got all the T-Shirts!
