I checked what appears to be the official website, but there is no mention of updates or versions. The software is listed as available for purchase, and that's it.
There is also a mention of the operating systems compatible with this application: works with Windows XP, Vista, Windows 7 & Windows 8. Will work with MAC with PC Emulator or Virtual PC, which allow Windows programs to operate on a MAC.
