FYI... Vector Linux 5.1 is more than three years old and is no longer supported. Sure, folks here will help you if they can but there are no security patches or updates to packages being issued. Running VL 5.1 now means having lots of known security vulnerabilities on your system. Upgrading to VL 6.0, 5.9.1 or 5.9 is highly recommended.
