An updated version that contains a critical bugfix is available now. Only the people who received their download versions before February 28th, 2015 are affected. If you received your download version before February 28th, please go to the protected download section, download the updated archive using your personal username and password, use the updated archive to generate a new ISO and then install the fixed version. People who received the download version after February 28th or ordered the CD-ROM version are not affected and don't need to do anything.
The version affected is the one built on 14-Feb-2015. The version that contains the fix was built on 27-Feb-2015. But keep in mind that even with the fixed version the GUI will still say 14-Feb-2015. You need to go to "About->System information..." to get the correct build information about Hollywood and Hollywood.sys or use C:Version on Hollywood and Hollywood.sys.
