Minecraft Bukkit Server not updating

I have a bukkit server that was running on the dev build for 1.6.1 just fine, but now when I apply the new dev build for 1.6.2 and I start the server it just starts up on 1.6.1 for no reason. I use Mac OSX 10.7.5 and here are the steps I've done:
1. Stop server
2. Delete old craftbukkit.jar
3. Download the new craftbukkit build and rename it to craftbukkit.jar
4. Drag file to Bukkit Server Folder
5. Restart computer
6. Start server
So I did all this, and used the new 1.6.2 build, but it still launches as 1.6.1. I also tried downgrading it to the recommended 1.5.2 build, but it still starts up as 1.6.1. There are no Errors in the start.command terminal window (http://pastebin.com/wTxp8Wpb) and here is what it looks like when I launch 1.6.2 and see it (http://imgur.com/V1XPJY6) but I don't know how to fix this, please help!

 

You're clearly running the old build still. Double check the folder to make sure you have no other craftbukkit jar files and start script to make sure you are launching the correct jar file. If you are still stumped then show us a screenshot or pastebin of your folder and start script.

 

Thanks TnT, it worked! I got it fixed but now I get another error, [SEVERE] java.lang.NullPointerException.
Here is the whole start log now: http://pastebin.com/a7MQaTQM
Edit: I forgot when I get that and do stop I get this: http://pastebin.com/Gyzv5X7C

You edited your help.yml file and broke something. Try to either remove those changes, or remove it (back it up first) and let the server generate a new one.

 

TnT How would I back up the help.yml folder? (On a mac)

 

Copy it/move it to another folder on your system.

 

Here's what my help.yml folder looks like: http://pastebin.com/8vgCDzzW

TnT It generated a new help.yml folder and it's still wacky: http://pastebin.com/vA3VgQRG

Nevermind TnT I fixed it it turned out that my world_the_end and world_nether were broken. They work now!
