I bought it on Amazon, I went to my software library. There is no version number on this item, so there is no way to know if it is an updated version. Will that version of the paid version match the new release version number of the free version (6.4.2)? I spoke with Amazon rep and they could not find a version number either and said to contact developer. The reason I am suspicious is that the last time the developer issued an update, I downloaded it. All my extra furniture pieces that came with my purchased version disappeared. So I downloaded the Amazon purchased version again. Then I got a warning message the next time I used it saying that I was now using an older version of the software than the one that created the file.
