Mcmmo 1.7.2 server won't run

I have a small server that I'd like to reopen for my friends and I. It's been closed because of the 1.7.2 update. I see other servers are running Mcmmo but, mine will not run. Then, I kept the run open and this happened. Can someone please help, I'm not really sure what to do. I have no experience running a server.

 

Your Factions is unclaiming land by itself, you probably need to delete the Factions folder and reinstall the plugin for 1.7.2 Also make sure you have MCore 7.0. Keep a backup of the Factions folder just incase I'm wrong

 

We are running 1.7.2 dev builds of Bukkit and we ave reverted to an older version of factions pre Mcore and are using the beta before the latest of mcMMO with only a few minor glitches due to mcMMO not knowing the new block types etc

 

Well, now it's saying that my permission folder was empty. I Deleted the faction folder and then reinstalled the plugin and I got Mcore 7.0
