Bukkit

What steps will reproduce the problem?
1. Start the server

What is the expected output? What do you see instead?
I expect all plugins to tell they've been loaded.
Instead I get an error about DeathNotifier not loading.

What version of the product are you using?
2.2 (I think)

Do you have an error log of what happened?
2012-07-08 01:34:03 [SEVERE] Could not load 'plugins/DeathNotifier.jar' in folder 'plugins'

Please provide any additional information below.
I have just updated from 2.1 to 2.2, there were no problems before.

Some Error. I did download the NC-BukkitLib to the /lib but i have the error still. Thanks.

NC-BukkitLib should be downloaded to the plugins folder.
