Error code 1063

We have PostgreSQL 8.1 running on Windows 2000 for a few weeks now. Don't know what happened, the users reported a connection issue to the database and I found the service will not start. When
we try to start the service, it could not start claiming no error
returned. So, I go to the command prompt and run the following:

"C:\Program Files\PostgreSQL\8.1\bin\pg_ctl.exe" runservice -N "pgsql-8.1" -D "C:\Program Files\PostgreSQL\8.1\data\"
pg_ctl: could not start service "psql-8.1": error code 1063

I tried to Google that error code, but come up with nothing. Can someone
tell us what this code means?

Last few things in the logs is:

2006-06-12 08:50:18 LOG: autovacuum: processing database "postgres"
2006-06-12 08:51:18 LOG: autovacuum: processing database "ohc"
2006-06-12 08:51:18 LOG: received fast shutdown request
2006-06-12 08:51:18 LOG: shutting down
2006-06-12 08:51:19 LOG: database system is shut down
2006-06-12 08:51:19 LOG: logger shutting down

I guess it has been down sine then, but the users have not used the database.
