Hi Daniel,
Thanks for your updates.
I would like to confirm if you can activate and use the Office normally before you uninstalled it? If so, the issue may be caused by undeleted cache. In this scenario, could you refer to this article to completely remove the Office 2011 for Mac then reinstall it to see if the issue will occur: http://support.microsoft.com/en-us/kb/2398768 ? This article requests deleting more files to remove the Office 2011 for Mac.
We appreciate your continued efforts and patience.
Best Regards,
Iris He
