zexus,
I've never seen that error here before. A quick google search didn't offer much help.
If you get that error again, could you please start a new thread in the
Site Feedback & Support forum? The main reason is that I'd like to find out if others are having the same problem and allow us to find out what the cause is based on what each user has in common. Plus we wouldn't let this "awesome" thread get sidetracked with off-topic tech support issues.
Hopefully this was a fluke and it won't happen again.
Thanks,
Alex
