New Radiohead Album is Great

I'm listening to the new Radiohead album right now.
I paid nothing for it, and it feels great.

I love you Radiohead.
I'll be buying a hard copy of this album now.
It's faster than their previous stuff, but its still great.
Nice melodies, and structure.

The Dreaded Final Cut Pro "File Error: Unknown File"

I'm getting a re-occuring error that is starting to chap my ass(I've since run out of chapstick).
I've seen others with similar problems here.
I'm trying to submit video to Current TV, and according to their best practices, which is smattered with lovely engrish phrases like this one:
"2. Select “Expert Settings” and clicking the “Share” button."
I'm supposed to export using Quicktime Conversion, using the LAN/Intranet Setting(an h.264 compression). I keep getting the same "File Error: Unknown File" no matter what. I've tried creating new timelines, new projects, Saving As, Saving a copy, exporting the full qt .mov and reimporting it. Nothing works. I get the same thing every time. I'm getting quite pissed off as I've tried submitting other similar h.264 compressions that are working.
I've even tried exporting the movie and sending it to iMovie. I get this error:


What the hell? Is this a quicktime problem if its happening in both FCS and iMovie? Can anyone save me from this infernal digital damnation?
I'm running an Intel Mac Mini 2 GB RAM 10.4.10 FCS2. Any suggestions would be greatly appreciated.
