How do I correct this? <Begging voice> Please <\Begging voice>

[root@ueserv1 opt]# rpm -iv FirebirdSS-1.5.2.4731-0.i686.rpm
Preparing packages for installation...
package FirebirdSS-1.5.2.4731-0 is already installed
[root@ueserv1 opt]# rpm -ev FirebirdSS-1.5.2.4731-0.i686.rpm
error: package FirebirdSS-1.5.2.4731-0.i686.rpm is not installed

(ibadmin reports 1.5.0.4288, RC9 which is what I thought I was running)
(then I tried to rpm -uv which helen says is a no no, now I'm stuck)
