need help wont load

Hi i am getting this message when i try and load up the mod.  it worked before and recently after i wiped my server it stopped working. i have changed nothing and have done the recent update.

Failed compiling 'RaidableBases.cs':

1. No overload for 'CanAcceptItem' matches delegate 'Func<BasePlayer, Item, int, bool>' [CS0123]

(RaidableBases 59 line 8702)

2. 'Sprinkler' does not contain a definition for 'TurnOn' and no accessible extension method 'TurnOn' accepting a first argument of type 'Sprinkler' could be found (are you missing a using directive or an assembly reference?) [CS1061]

(RaidableBases 31 line 8846)

heya, you need to update the plugin. those errors are from an older version

I have installed the newest version a few times and still get this error.
