We regret having been silent recently. We are very hard at work on the new release. We hope to have it out soon and it will address many of the DRM problems that some of you have been seeing, including content portability across computers. We appreciate your patience.
However, because DRM systems are very complex, and the range of computers and environments they are used in are so varied, the problems are often rather complex as well. I am not finding the forum a very good way to support those of you who are having problems. Therefor, please submit a support incident at www.adobe.com/support/digitaleditions/.
