GeneXus - Error al abrir una kb en una version mas actualizada de Genexus

Hola a todos:

Es la primera vez que trabajo con Genexus y tengo el siguiente problema: estoy tratando de abrir una kb que se desarrolló en la version 9.0 y yo tengo instalada la Version: 10.1.34783 U3. El error se muestra en la imagen que subí, pero específicamente los errores que presenta son:
