How to get LanguageTable in runtime

Hi there, Is there some way to get LanguageTable in Runtime? I have tried few thinks, but no luck so far. Any tip? My AddIn project is "IProjectServiceExtension".
ILanguageTable languageTable = m_Project.Parent.Parent.Workspace.ActiveProject.LanguageTable;
ILanguageTable languageTable = m_Project.LanguageTable;
Both returning null. Any help appreciated. Regards, Jaroslav
