Well, problems related to working imports is one thing, but I think some credit is due: DAO came out five years ago! A lot of people will have lost their savegames and might not even have the game installed anymore or have played it on a different system. Hell, A lot of people will have their one perfect playthrough that they wish to keep, and don't feel like playing through the game again.
This is an excellent solution, that does not depend on what system you're using, having to reinstall the game or having the save preserved. They could have gone all KOTOR on us and basically nullified any choices we've ever made, or forced us to make an enormous bank of saves to exchange if we had lost ours, but they went through the trouble of making it possible to create all of our choices in under 30 minutes.
The keep was a brilliant idea and a service to the fans of the series. Not that I disagree that it's sad if some people are having problems with importing the decisions and I hope it isn't too common.
