That is correct, we dropped support for SQL 2000 in version 184.108.40.206 as indicated in the release announcement for that version back in July 2010 http://www.mojoportal.com/mojoportal-2348-released.aspx
I also initially asked for input about it back in March 2010 in the blog where I asked "Anyone Still Using SQL 2000", and the feedback indicated only a very few people were using it and even those few were supportive of us moving forward and dropping support for SQL 2000 since it would make it easier to manage development going forward to have a single data layer for SQL 2005/2008/SqlAzure. Prior to that we had introduced a separate data layer for SqlAzure because it was impossible to have a data layer that was compatible with both SQL 2000 and SQLAzure because SQL 2000 does not support nvarchar(max) and SqlAzure does not support ntext data types. By dropping support for SQL 2000 we were able to change all ntext fields to nvarchar(max).
Sorry for the inconvenience but time and progress move forward. I would ask your host about migrating to SQL 2005/2008.
