Adobe Flash Player 10.3 is the supported player for older Intel-based Mac OS X 10.4 and 10.5 systems. On some systems, users sometimes see a blank or black screen while attempting to play protected video content on services such as Amazon Instant Video. The Adobe Flash Player automatically downloads a specific module used for protected video content playback on first use.
An incorrect Adobe Flash Access DRM (Digital Rights Management) module deployed in early December 2011 caused this bad video playback behavior. The bad module has since been replaced.
Systems that downloaded the incorrect module cannot play protected video content until either 1) a Flash Player upgrade or 2) removal of the bad DRM module. This document describes how to remove the incorrect DRM module so the Adobe Flash Player can upgrade to the corrected DRM module.
