metadata Library: instmemx1-Index violation

Hi all, I am new to webMethods and have now installed the base products on
an XP machine with SQL Server 2005.

When I run the setup of mlivp to setup metadata Library the setup runs
(after a few minutes) into the same exception again and again and
does not stop at all:
