Visual Studio problem

[Mark]

Our project goes live in 2 days and we have a big problem! We are using
Windows Forms databinding and the Entity Framework (SQL Server backend).

Bizarrely, Visual Studio has started playing up, for some reason it keeps
unlinking datasource types from bindingsources! It's a pain in the editor
with errors opening forms but I've kind of got the hang of hacking into the
designer.cs and manually putting them back in but if you don't notice before
you release the software then the client gets databinding errors, seemingly
randomly! This means we have to test every aspect of the application after
every small change - nightmare!! %|

I have tried another machine and still the problem persists.

Has anyone else seen this, and solved it?

What version and edition of Visual Studio? Are all service packs applied?
While we're at it, any third party add-ins installed? I seem to recall some
similar posts related to VS 2005 prior to service packs, but nothing more
recent.
