The 184.108.40.206 patch is now live.
This fixes a problem which was preventing some movies created in 1.1.4 from loading in 1.1.5; specifically, movies which featured a sound file attached to a loudspeaker set object. These movies will now load correctly.
(You may experience problems if you try to get the upgrade tomorrow - 12 May 2009 - while we're doing the Web site upgrade. If so, just try again after 6pm GMT. Cheers.)
