AutoCAD Civil SP1!!!

Hello everyone!... In a continuing effort to provide high quality products, Autodesk has released AutoCAD Civil 2009 Update 1, which fixes or addresses a variety of issues discovered by customers and by Autodesk's internal testing team.
Before applying this update, make sure that any customizations made to the user profile (such as, customizations made to the support file search paths, print file customizations, printer support file paths, redirections, custom template settings, and so on) are exported to a secure location, then imported and reapplied after the update has been successfully installed.
Also... Autodesk released the AutoCAD Civil 2009 Object Enabler; it is a 32-bit freeware application that allows object data created in AutoCAD Civil 3D 2009, AutoCAD Civil 2009, AutoCAD Land Desktop Companion 2009, or AutoCAD Land Desktop 2009 to be accessed outside of those environments. This Object Enabler can only be applied to 32-bit applications in a 32-bit Operating System environment.
As part of the Product Update 1, Autodesk has also decided to make updates to the Object Enabler. The most significant change is that this Object Enabler will now detect and install onto NavisWorks 2009 applications and Impression 2009.
If you are encountering crashes opening drawings from previous versions of Civil products you may need the AutoCAD Civil 2009 Object Enabler Mentor Grid Coordinate System Files. These files will allow the Object Enabler to open previous version drawing files that have a coordinate system assigned to them.
... Please remember to refer first to the README file for installation...
