Mongodb не может запускаться на окнах?

когда я попытался запустить mongodb с помощью команды "mongod.exe" в командной строке, он выдает следующую ошибку.

C:\mongodb-win32-x86_64-2.0.6\bin>mongod.exe
mongod.exe --help for help and startup options

old lock file: \data\db\mongod.lock.  probably means unclean shutdown,
but there are no journal files to recover.
this is likely human error or filesystem corruption.

Я действительно не могу начать mongodb.. Помогите мне запустить mongodb как службу Windows и исправить ошибку. Я уже читал руководство по установке и следил за тем же, но все же выдавал ошибку.
