I recently purchased the NIDNTT and NIDOTTE modules. The CD's I received contained version 1.0 of both of these modules. These two CD's do not require unlock codes to install the modules. However, the latest version of NIDNTT is 2.0 while the latest version of NIDOTTE is version 1.1. The AccUpdater Widget tells one that the updated versions are available on the Zondervan Essential Bible Study Suite, Personal Growth Bible Study Suite, or the Scholarly Bible Study Suite. I happen to have these packages so I used the Essential Bible Study Suite CD to update my modules. Every thing worked fine until the end of the installation when I was asked for the unlock codes. Since I do not have the unlock codes, I clicked cancel and the installation terminated. However, both of modules were updated and appear to work properly, and the AccUpdater Widget sees them as being the current versions. Do I need the unlock codes for the updates? If so, how do I obtain them? I noticed some interesting behavior with these two updated modules. I happened to remove both of them from the available modules using Arrange Modules. When I added them back into the available modules, I was asked for the unlock code for NIDOTTE which of course I do not have. Interestingly, I was not asked for the unlock code for NIDNTT. There is a simple fix to this problem. Just delete the updated NIDOTTE module, reinstall the original version from the NIDOTTE CD and then update it using the Essential Bible Study Suite CD.
