Today, the SpeedGrade CS6 (6.0.4) update was released.
The SpeedGrade 6.0.4 update includes the previous 6.0.1, 6.0.2, 6.03 patches. Please install this update, even if you have installed the earlier patches.
If Adobe Application Manager hasn’t already told you about this, go ahead and check for new updates by choosing Help > Updates in Adobe Bridge. The best way to check for updates is by closing all Adobe applications other than Adobe Bridge, and choosing Help > Updates in Adobe Bridge; this ensures that all processes related to Adobe video applications have been quit and can be updated safely.
Ideally, you should install the updates automatically as described above, but you can also directly download the update packages from the download page for Windows or Mac OS.
