This is what comes up when I try to run PreciousSto nes plugin. Please help, it doesnt run on my server.
This MIGHT mean that that plugin might not support your CraftBukkit 1.4.6 version (as what I see in the window). This happened to me when I was installing WorldEdit and it didn't support CraftBukkit 1.4.6 but then I found a link in the post saying the 1.4.6 version for CraftBukkit. Look at the post again and try to find a 1.4.6 version. Otherwise, wait for it to update.
