JFC Apple. 26.3 breaks Compressor 4.7

Anyone who was hanging on to Compressor 4.7 for DVD and BluRay authoring. 26.3 breaks 4.7 so that it won't even launch. It's so incredibly frustrating. I may just ditch all of the FCP suite. No warnings when they removed DVD/Blu authoring and now this. In a fucking point release not a major update. Just irresponsible and hostile.
