Sharepoint 2010 Search Error

Search is not giving any results in SharePoint site. Checked central Admin, Crawl component is in recovering status from a very long time.

I am getting below error while trying to delete the recovering crawl and add a new crawl component at Toplogy

Errors were encountered during the configuration of the Search Service Application.

System.NotSupportedException: Specified method is not supported. at Microsoft.Office.Server.Search.Administration.SearchConfigWizard.UpdateSearchApp() at Microsoft.Office.Server.Search.Administration.SearchConfigWizard.ProvisionSearchServiceApplication() at Microsoft.Office.Server.Search.Administration.SearchConfigurationJobDefinition.ExecuteTimerJob()

Please help
