Oracle - Listener Oracle 10

Hola, reinstale el Oracle 10 (antes andaba ok), ahora cuando trato de levantar el servicio de TNS me da "Error 2: the system cannot find the specified file". Luego cuando voy a ejecutar el lsnrctl >>start me da Failed to start service, error 2.
TNS-12560: TNS:protocol adapter error
TNS-00530: Protocol adapter error
32-bit Windows Error: 2: No such file or directory

mi Listener.ora es:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = CRM)
(ORACLE_HOME = c:\oracle\product\10.1.0\db_1)
(SID_NAME = CRM)
)
)

LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)

TRACE_LEVEL_LISTENER = USER

...y el tnsnames.ora....
CRM =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = CRM)
)
)

...alguna sugerencia?????.desde ya muchas gracias..
