Not able to login to SCSP console

HI,

I've recently installed SCSP 5.2.9 on Server 2003.

It was installed properly.

First I installed server and then console.

But after the installation, when I tried to login I'm not able to do so.

So I uninstalled everything.

But now when I'm trying to install it again, it's taking the existing database instance.

How can I delete that instance so that I can start everything fresh.
