I believe I've got all the enhanced, ODNT, and Stardock Central installers properly updated now. Use the form at https://www.stardock.com/support to get the enhanced links and serials or your CM/SDC as appropriate.
Customers who's ODNT subscriptions have expired, please contact sales@stardock.com with your serial. They have a link that you can use with the CM to get 3.51.
Any other specific questions on this, email kwilas@stardock.com rather than support. They have enough with the people who aren't reading here for info on this matter.
