Unserialize/Reserialize Final Cut Pro & Why does apple hate me?

Here’s two quick video related snafu’s I’ve run into today.

I have had to unserialize a copy of FCP and then put in a new (the correct one, technically) serial number. It turns out that unless you want to reinstall everything, then the file to find is located in Library/Application Support/ProApps and it is called “Final Cut Studio System ID” Delete it with fcp closed, and then open it up again

The second one is because Apple dropped a turd of a quicktime update that completely disabled (worse actually) exporting out of After Effects. Here is the apple discussion thread.
I followed what a few people suggested and used Pacifist to install quicktime 7.3.1 with no ill effects.

Thanks Apple.
