I actually started having this error when a database was upgraded to
9i, but after upgrading to VS 2003, I am now unable to update
anything, quite in line with this message.

What do I do about it? I have been using VS as a tool to create
tables, make changes, and when the change is problematic, script the
change. I can now do none of these things. What is the Microsoft
suggestion for this loss of functionality? I know I can use Visio for
some of this; has it been upgraded to handle non-destructive table
changes?

Thanks for any insight.
