I recently was unable to export, turned out is was a black video and an effect.
Look at the time/clip in AME when it crashes.
Then go to Premiere and see if you can spot something unusually at that time or clip.

Along with Ann's comments, and the link to the Adobe KB Article, on Error Compiling Movie, some other things to check for:
- Gaps in the Video - if you have any, that are not covered by some sort of "overlay," whether a Title, PiP, etc., and you DO want the black that appears, just create Black Video (New Icon on the Project Panel) and Trim it to fit that gap. If you do NOT want the gap, just delete, or close it up.
- Check for odd Assets, where the program is stopping/hanging. MP3's, and some MOV's, can be problematic.
- Check for overly-large Still Images - though PrPro CS 5, and above, can handle them better, many of them DO draw on resources, while they are being processed.
There are some issues with Canon MXF files new to CS6.
Have you updated to 6.0.2?
I went through a compiling errors period recently as well. everything was working beautifully until i installed a quadro 4000 for mac video card and upgraded to 10.8 and 6.0.2. the problem was, my nvidia driver wasn't mountain lion friendly. i updated the driver and things got back to normal. i see you're not on a mac, and you may not have an nvidia card, but if i were you, i'd check my drivers to see if they're up to date. good luck, man, i've still got ptsd from getting so many compiling movie errors
I am having the same issues... I have a Canon XF100 and have just upgraded to a brand new imac (as powerful as you can get) and CS6 and am getting CONSTANT issues, unable to render, unable to export. Always saying "Error Compiling Movie - Unknown Error". I NEVER had these problems with CS5.5 on my MacBook Pro. Sometimes its fixed by removing a fade to black or sometimes I have to reboot. I have even started a new project and copied the footage across to a new project and exported and its worked fine... but each time there is a new issue and going through the troubleshooting is very time consuming. I am enjoying the new features of CS6 but I am not sure it's worth these headaches.
I am encountering Compiling Errors (error unknown) evertime I try to export media. I have footage from a Cannon XF100 (.xmf H.624) and........
What is .xmf H.624 ? I am using XF100 footage successfully since the 6.02 update.
We have really put the machine through paces over the last month and it has been a champ.... finally.
Try posting your system specs. And do you have any .MXFs with visual or audio glitches?
