We had to update the MindPlan R3 installation databases on 28th of january 14:30 CET, because a few new design elements were missing both in the MindPlan sample database (wmindplan.nsf) and in the design template (wmindplan.ntf).
The design elements are used for the new export profile "Send a meeting invitation containing the agenda":

If you've already installed/updated to R3, please download the installation database again from the download area and run the update installation:

There just choose "MindPlan templates" on the installation components page:

This installs the corrected templates and runs the design upgrade wizard. The other parts of the installation have not been changed.
Sorry for the inconvenience!
A last note regarding the update+ customers:
I've talked to our update team that is currently preparing the R3 license keys, the release notes document (German/English) and the update+ mailing. They said they need a few days to send the email with all the information.
If you want to update before getting your update license key, you may request a 21-day evaluation key with the request function built into the application.
To update, first create a backup of your existing MindPlan databases. After running the update installation and updating the application and database's design, please open the MindPlan configuration database in the Lotus Notes client and execute the agent "1. MindPlan update 2.1->3.0\Add work package node". This creates the new project management node type "work package".
