Just wanted to post a quick note to say that I got in touch with Mike (the developer) and he quickly informed me that the new version is a FREE upgrade for existing purchasers. You can get your license by visiting the help section of the website and entering your e-mail address for lost licenses. If your e-mail address doesn't work just e-mail him and I'm sure he'll get it sorted in no time.

Delighted with this FREE update and the developer's prompt and very-helpful e-mails. Looking forward to get my teeth into this very exciting new version.
