bshayhoe, I split your post out of the Troubleshooting thread, which is not for support, and into its own thread in the Bukkit Help section for higher visibility.
You have to modify the CraftBukkit line of the batch file to match your CraftBukkit file. If you have a file named craftbukkit-1.7.2-R0.3.jar, you have to set the line to match it, as shown here: java -Xms4G -Xmx4G -jar craftbukkit-1.7.2-R0.3.jar
