Ok, made some changes:

The dll:

using System;
using System.Collections.Generic;
using System.Xml;
using maddox.game;
using maddox.game.world;

}

What modified:
Changed the old singleton implementation to a better one (without double locking) and renamed it to Translations
Moved the translationsMessages to the sendMessage Class. Added reference to the Singleton Translations "private static Translations Translator = Translations.GetInstance;" so GetString() could used in the sendMessage class (Translator.GetString(...))
Added a UseConfigFile to the singleton to load the language file later (in cs from mission).

To load the Translationsfile into the singleton use:
private Translations Translator = Translations.UseConfigFile(localizationFilePath);
in mission file cs.


Should work now, couldn't test it at work, only short time in coffee break for modifications
