Plugin Help Worldguard not loading

Hi one day my worldguard plugin has crashed and didn't work anymore. I tried to install other versions but I need the lastest. Now the server doesn't load the plugin and ignores it! HELP!!

 

@fedecek22 You haven't really provided any information. You've said there's a problem with loading, but that's it. Can you provide a paste of the stack-trace (console error)? Can you say what version you're using? Can you say what version of Bukkit you're using?

 

I found the error
10.02 16:37:25 [Server] INFO org.bukkit.plugin.InvalidPluginException: java.lang.NoClassDefFoundError: com/sk89q/minecraft/util/commands/CommandPermissionsException
10.02 16:37:25 [Server] ERROR Could not load 'plugins/WorldGuard.jar' in folder 'plugins
I didn't do anything only changed the version of worldguard and now all the plugins of sk89q does not load. D:

 

@fedecek22 What other plugins do you have?

 

The working plugins I have are:
MultiWorld, IronElevators, PlugMan, ServerMotd, CleanChat, AntiCombatLog, MassiveCore, AdminFun, Vault, PlotMe, KitsPreview, PermissionsEx, CombatTag, CoreProtect, CrackShot, iDisguise, JukeLoop, PvPTitles, ZavAutoMessager, ClearLag, BungeeCordLib, ProtocolLib, Essentials, Citizens, EssentialsProtect, ItemCase, EssentialsSpawn, Multiverse-Core, EssentialsAntiBuild, ItemSlotMachine, WarpPortals, AuthMe, MyPet, EssentialsChat, Timeismoney, HolographicDisplays, Factions, AdminTP, ScoreboardStats
The non working plugins are:
WorldGuard and WorldQEdit

 

@fedecek22 WorldGuard requires WorldEdit. If you changed the version of WorldGuard, change WorldEdit too.

 

They're both up to date on version 6.0
By the way I had also CraftBook that is a plugin of sk89q and even this one didn't work although I didn't change version or config.
