Hotfix - Autodesk Activation Update - After you activate and then restart your product, you receive error 0.1.0011 or 11.1.6011 and are required to reactivate. This problem can occur for Autodesk's 2006 & 2007-based products on computers with SATA Raid controllers. Important: If this update is applied to a computer that does not have a SATA Raid controller, the license on that computer will be broken. You will need to reactivate the product to repair the license.
