I just purchased, downloaded and installed netobjects fusion v12. I have an existing local site (which is also published to a remote location) that I had been maintaining with a temporary installation of NO Fusion v 12..however when I now try to open that site, I get a message saying that the site had been created with a later version of NO Fusion. This cannot be possible, I think, since I just downloaded and installed the latest version. It is vital that i am able to open this site to maintain and publish it.
I am an experienced computer user with VB and SQL programming background, but am a relative newbie to website maintenance.

Grateful for any guidance on how to open this existing site.
