Please be patient with my ultra n00bieness.

I recently was trying to uninstall vsftpd via Synaptic on RH9 and came up with the error
Sub-process /bin/rpm returned an error code (255)
Then I tried to uninstall it manually in terminal with root privalages of course. I first checked to see that it was installed by running
rpm -q vsftpd
and came up with
vsftpd-1.1.3-8
So now assuming that it is installed I run
rpm -e vsftpd-1.1.3-8.i386.rpm
and get
error: package vsftpd-1.1.3-8.i386.rpm is not installed
So I thought maybe if I install it over itself it will fix this so I can cleanly uninstall it. I dl'd the package and the tried to install it using
rpm -Uvh vsftpd-1.1.3-8.i386.rpm and get
Preparing... ########################################### [100%]
package vsftpd-1.1.3-8 is already installed
Arrrrgh
Can someone please offer me some suggestions on how to fix my problem here?
Thank you
