Votifier Issues....

So I just recently switched my MC server to a new host, changing the IP, but keeping the same domain (mc.awnw.net) and when installing Votifier, I get this error on startup:

Code:

Any help as to why this is occuring would be great. Thanks!

 

I recommend asking for help from the plugin author on http://dev.bukkit.org/server-mods/votifier/
Either a comment or a ticket there would suffice.
