Error 3021 en tiempo de ejecucion:

[crucifijo]

Hola amigos fijense que estoy haciendo una puequeña aplicacion de horarios para unos profesores, tengo creado un modulo de profesores donde son altas, bajas, cambios, eliminar, ya me he conecte a la base de datos y he puesto el codigo mi problema es que cuando le doy eliminar registro me manda el siguiente error "Error 3021 en tiempo de ejecucion:
El valor de BOF o EOF ES True, o el actual registro se elimino; la operacion solicitada requiere un registro actual." y no se que hacer para corregir el error.

Nota mi base de datos esta hecha en access 2000, les dejo el codigo esperando que me puedan ayudar gracias.
