Cubase SX, the professionally priced (expensive) music and audio authoring suite from Steinberg, has a new major version, Cubase SX 3. People who purchased or upgraded to Cubase SX 3 for Mac OS X should download the latest patch to 3.0.2.622.
Cubase SX 2 users (like me) are advised to update to the latest version, 2.2.0.39. Steinberg gets points for trying to clean up their lousy web support for their products, but they have broken all of their old links in the effort, including the SX 2 update link on their current site (which goes to an incorrect URL for version 2.2.0.33). I know about 2.2.0.39 because I went straight to ftp.steinberg.net to look around, and found the correct file locations. It appears that the 2.2.0.39 update is not a complete update (only 5 MB compared to 2.2.0.33, which is 20 MB).
The correct update process for SX 2 users (for Mac OS X) is to download and install the 2.2.0.33 update if you haven't already (including the Syncrosoft license control software update), then download and install the 2.2.0.39 update. The 2.2.0.39 update will not run correctly without the 2.2.0.33 update installed (it complains "File not found: Cubase SX").
The fixed version of the license control software can also be obtained directly from Syncrosoft.
