Yesterday, we reported that Google Quietly Released AdWords Editor 7.0. We thought they did it quietly for a reason, but it turned out - they blogged about it soon after and people began installing it. I was hoping they wouldn't announce it fully until they worked out the kinks.
Now I see a post from AdWordsAdvisor in that WebmasterWorld thread announcing a bug with the automated backup feature. Let me quote you:
We've discovered an issue with the automatic backup feature in version 7.0 (the 'Backup then Update' option in the upgrade prompt). If you have unposted changes and comments, and you haven't yet installed the new version, please back up your changes by exporting an archive before upgrading. You can see detailed instructions for manual backup, as well as what to do if you've already installed version 7.0, in the Help Center: http://www.google.com/support/adwordseditor/bin/answer.py?answer=134497
So, if you downloaded it, be careful and read the quote above.
