I've used Vault plenty of times flawlessly, and I'm not sure what's going on currently. I'm setting up a server using Towny, which I've never used before, and for the economy I'm using iConomy which I have used. For some reason when I place the vault.jar in my plugins directory it does not create a folder prior to restarting the server. Though, if I do /pl in-game it shows Vault as being loaded. Except it keeps giving me errors if i try and use iConomy commands, or Towny commands. Creating a town just pops up with saying "null" and using /money in-game tells me an error occurred trying to use it. I figured this is because it isn't linking with Vault correctly. Any help?

Vault has no configuration, if you have errors somewhere you'll need to look at your server log to see what is actually the problem at startup. There are no issues currently with the Vault connector for iConomy 4/5/6
