Moonraker, the email you're describing is the purchase receipt that Plimus sends you, with a subject line containing "Receipt for your Payment" and your purchase reference number. You should have received a second email from support@ldw.com with a subject line containing Virtual Families 2: Our Dream House, the version you purchased (Windows or Mac) and Full Version Order Information. If you don't see that second email, please check your spam folder, since spam filters often catch those emails.
You can do as arnie mentioned and open a
Support Ticket and Heather will supply you with the information you need. You can also obtain the information contained in the confirmation email by using the procedures I explained in
this post. You will find the download link for the full version there.
