We did have a bad module for Build 126.96.36.199 on Mac OS 64-bit. Perhaps you 'cached' that bad module.
If you look at finder in:
See what library you have down there. Most likely you have the one that was corrupted. (adobecp64-301806-1.plugin).
Also, we've updated the player to build 233. Maybe it's just best you upgrade your Flash Player and it should re-download the (newer, clean) DRM modules
188.8.131.52 also has a corrupt module that tested OK internally. We're refreshing this today.
Did this get pushed? The current version of FP for MacOS is still 184.108.40.206.
If the new runtime was pushed, will the old versions see 3343/3344 events and update accordingly?
