Bukkit

Hello, I try to download all Total suite : TotalEvent, TotalQuest, ...
It isn't easy to find the links for download all, but I get it.
I put all files on my bukkit server. When I reload it, plugins are on. Main menu are visible and usable.
Error :
When I try to create NPC. I select them, but when I click on "Add NPC" nothing happens.
When I try to edit Objective, or reward, or requirment, no Objective, reward or requirment is find. However, I put it in my plugin folder.

Can you help me about this ?
Have you need more info ?
And sorry for my bad english :/
