539763 Problems with Plesk and MSSQL / Webadmin URGENT 2

Ok the problem is that I have installed plesk and mylittleadmin When I go to DB in my plesk panel, and press the icon (webadmin) it directs me to server does not exist. Its using [login to view URL] here in the link for webadmin(mylittleadmin), but even [login to view URL] is not reacting alone. Please be experienced in plesk before obtaining or bidding on this task. Will of course be no cure no pay. I am willing to pay good, I just need it done immediatly.
