YARGH! We just announced the release of 2.5, and have increased licenses on the multi license version to 25 domains from 10. All existing customers get the increase, and the price for new customers is the same as it was for 10.
2.5 has a bunch of new enhancements to some features to get ready for big changes coming from google, and 3.0 is fast on it's heels
If you are having trouble getting in to add the new domains let me know on ICQ (in my location field) or send a ticket via relinksoftware.com's support system.
Remember after adding a domain to regenerate the archive, then download.
