Thanks for posting the issues that you were having with Advertising Manager. I believe that the issues that have been posted about have been fixed in version 3.4.10.
However, there are some people who have clicked 'its broken' in the compatibility widget. I want to identify any issues with this plugin ASAP.
If you are still having issues, please let me know the following:
1. The exact error that you are getting.
2. Your PHP version. If you are having problems finding the PHP version, install the PHP Info plugin: http://wordpress.org/extend/plugins/wordpress-php-info/
3. Your WordPress version.
Before I make any new features, I want to make sure that there are zero bugs in this version of Advertising Manager. If you see something please let me know. If it is easier to discuss directly with me, please feel free to contact me via skype (switzer).
