[Gvsig_usuarios] error al cargar SEXTANTE

[Chiara Porcu]

Hola a todos/as! 
tengo un problemito...  trabajo con la versiòn 1.1.2 de gvSIG en Windows xp. parece que Sextante no funciona màs corectamente. cuando voy a llamar la aplicaciòn me aparece el error que pego en la mail. la cosa rara es que hace unas semanas funcionaba perfectamente. la ùnica cosa que he variado es la instalciòn de NavTable. puede ser que esta crea conflicto o a lo mejor la he instalado no correctamente? la versiòn de NAvTable es la 0.2.2. 
Gracias,
Chiara Porcu
