Cannot un-mute Line2/Mic2 on LiveDrive II

I have a Live! Platinum with Live Drive-II on a Win2000Pro SP4 system.
Everything was working fine.

I had to format the drive and re-install the OS+Applications (for a
unrelated reason..).

Now, after installing the Creative Drivers LiveDrvUni-Pack(ENG).exe dated
Feb 28, 2003 from
http://us.creative.com/support/downloads/download.asp

I have the following problems

1. The Line2/Mic2 option in the Playback mixer cannot be un-muted. This is
with the knob next to it set to Mic. A microphone plugged in Mic 2 on
LiveDrive would not produce any sound through the speakers.

2. The card is detected as Live! (Value) in the Device Manager. Is this the
way it should be? Maybe this is the problem..

Any ideas how to fix this? There has been no hardware changes since before
the OS re-install. So, the problem is not with connections or PCI slot etc.

What is a good way to remove all vestiges of any previous driver and
re-installing Creative drivers?

Thanks.
