When I get a message in Dopus that a new version is available, I click on the link to go to the website to download it. That website seems to no longer exists. All I get at the main site gpsoft.com.au/ is a IIS 7 welcome screen. Where can the latest download be found? Does Directory Opus still exist?
What about this address? It works here.
That site/URL works fine for me and doesn't seem to be running IIS 7, either.
Just a guess: Have you edited your hosts file to point gpsoft.com.au back to localhost/127.0.0.1, and are you running your own default IIS 7 install?
