I have never given an extension this low of a rating, however this component is very frustrating. It's VERY buggy and there is virtually NO support for it. You can leave a request in the forums of their site but you'll be lucky if you ever get an answer. After going through the motions with this component I cannot log into the back end (administrator) side of the new 2.5 install. No one seems to know the answer to this so basically this component is useless.
Joomla should have a much better way for us to migrate over to 2.5. I'm completely lost on how I'm going to do this. This certainly is no help whatsoever
