He tratado de instalar WebSite X5 Professional 10 en Windows 10 Home, pero no funciona adecuadamente, trabándose cuando quiero agregar texto.  Dá el siguiente aviso al iniciar:

10/09/2015 4:10:28 p. m. [EXCEPTION] Item has already been added. Key in dictionary: \'Calibri Light\' Key being added: \'Calibri Light\' mscorlib at System.Collections.Hashtable.Insert(Object key, Object nvalue, Boolean add) at System.Collections.Hashtable.Add(Object key, Object value) at WebsiteX5.BL.FontsLibrary..ctor() at WebsiteX5.BL.BLManager.fontLoader() at System.Threading.ThreadHelper.ThreadStart_Context(Object state) at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ThreadHelper.ThreadStart()

Agradeceré su ayuda para resolver ésta dificultad.
