Lately when exporting using compressor it tells me it can't statt the process "Pleaase restart your computer or verify your installation is correct."

Has anyone encountered this before and have a remedy. Restarting doesn't help.

That's usually the case when the OS or directory structure needs a good cleaning. Download and run Onyx for your version of OSX and use ALL it's cleaning and maintenance routines. If that doesn't clear your problem get a copy of DiskWarrior and fix your directory.

If either of those apps don't get you fixed up you might have a hardware-related problem such as memory addressing.

Let us know what happens.

Thanks. I eventually surrendered to the idea that my directory was screwed up (I recently had to re-install the OS). I scrubbed FC off the hard drive and re-installed it. Hopefully that did the trick. I'll know later today.

That's overkill and a lot of wasted time. Get a copy of DiskWarrior and use it in combination with Onyx to troubleshoot issues like this in the future.

It's also a good idea to run both those apps on a regular basis to keep things "tuned up" and running smoothly - once a month is a good routine. But of the two, DiskWarrior is by far worth it's weight in gold - platinum even, you should consider that your life-line to serious OS and directory issue-fixing.
