I am using a neato XV-11 lidar and I am able to record a bag file. However when I run the launch file in this tutorial http://wiki.ros.org/hector_slam/Tutor... with my bag file I get the following error

[ INFO] [1455077561.968539391, 1454655528.267204049]: lookupTransform base_footprint to neato_laser timed out. Could not transform laser scan into base_frame.

Can anyone help?

When copy/pasting console output it's better to format it as Preformatted text (the button with 101010 on it). That way illegal markup (like the [ INFO ]) does not get filtered out (your error message was invisible).

There was another ROS Answer thread about that exact error (well, almost exact--it wasn't about a neato_laser, just laser), and in the thread it was determined that this is just an informational message (hence the [INFO] label) that occurs in the short time before the transform has spun up.

In other words, all you have to do is wait and the problem will go away on its own.
