Unfortunately, I don't think it's possible to update the software to a new version since there is no official website or a download to save it to your PC and apply it to the current installation.
I've searched the web and all the related websites but couldn't find anything about the It's About Time. Also, at the time of release, the software has been deployed in form of CDs. It's known that developers didn't release any updates for the applications released on CDs a very long time ago.
