problem with ymessenger

I installed ymessenger on my Redhat linux 9.0. After that, I deleted it manual .
But when I want to install ymessenger again by command:
#rpm -i rh9.ymessenger-1.0.4-1.i386.rpm
The system reports:
package ymessenger-1.0.4-1 is already installed
Then I tried to erase it by command:
#rpm -e rh9.ymessenger-1.0.4-1.i386.rpm
it report that:
error: package rh9.ymessenger-1.0.4-1.i386.rpm is not installed
I don't know what it is. How can you solve this for me?

Thanhks alot!

:(

This is a real shot in the dark, but what happens with:

Code:

---

rpm -U rh9.ymessenger-1.0.4-1.i386.rpm

---

Other than that, if it came with the redhat disks, maybe try to reinstall with a software management utility (I am not familiar with RH, so I cannot say for sure what it uses)

How about trying

Code:

---

rpm -i --force rh9.ymessenger-1.0.4-1.i386.rpm

---

or

Code:

---

rpm -U --force rh9.ymessenger-1.0.4-1.i386.rpm

---

I installed it successfully! Thank you!
