Multiples errores en log.txt

Un par de preguntitas, me tarda un montón en cargar desde que actualicé a la 10.31 y ayer miré el log.txt y veo muchos errores que os pego aquí abajo a ver si me podéis decir como los puedo solucionar.
Y por otro lado, para actualizar a la 10.31 creé otra instalación desde el xp installer y me dejé la original en la 10.25, ahora que veo que todo va bién (menos estos errores) ¿puedo cepillarme la instalación original sin más, borrar la carpeta entera y ya está?

(Dá mas errores iguales pero no me deja postear mas de 12.000 caracteres)...
