I have been pretty busy in the cloud (see http://ninefold.com for details) but a few people have been asking for the holiday import wizard to be able to work with Office 2010.  It will now find the Outlook 2010 Holiday file if you have Outlook installed and it will run in Project 2010 but I have not been able to test that it performs correctly in Project 2010.  Can someone try and let me know?  Download the new version from here.
