repotools.bat -createTables error

Hi !!

I am unable to run "repotools.bat - createTables" command

Here's the error that I'm getting...

com.ibm.team.repository.common.transport.TeamServiceRegistryException: CRJAZ1126I The service "com.ibm.team.repository.service.internal.rdb.ConnectionPoolService" had some invalid configuration properties:
CRJAZ1125I The configuration property value "SQLSERVER" is not valid for the property "db.vendor". CRJAZ0818I Unsupported or misconfigured database vendor "SQLSERVER" for the property "com.ibm.team.repository.db.vendor". Check the server configuration.

Here is the teamserver.properties file:
com.ibm.team.repository.db.vendor = SQLSERVER
com.ibm.team.repository.db.jdbc.location=SERVER;databaseName=JAZZ;user=jazzDBuser;password={password}
com.ibm.team.repository.db.jdbc.password=PASSWORD

Also, I set up the the environment variable SQLSERVER_ABSPATH to the directory "C:\Program Files\ibm\RQM\server\server\sqlserver"

I have already done this guide: http://www-01.ibm.com/support/docview.wss?rs=3488&uid=swg21376702

Please, Could anybody help me?

Thanks in advance
Regards
