migrating to 6.5 errors, include+database

[BillionNamesGod]

Hi, I'm trying to mirgrate a site to NT 2000, Plesk 6.5 box:

The first include error, I got I replaced:

<!-- #include virtual="/folder/file.inc" -->

with

<!--#include virtual="/domain.co.uk_non_ssl/folder/file.inc" -->

The problem went, but it got worse now I get this:

Sorry www.domain.co.ukThere has been an error connecting to the server. Please contact the site administrator ::www.domain.co.uk

--------------------------------------------------------------------

What does this mean!!!

Also, how to get the databases over? I couldn't see any MSSQL tools? like Enterprise manager etc?
how do I get better error reporting?
