Vincent,

I am just now seeing this post, so I will just repeat what I said in our email exchange back in December in case anyone else runs across this thread. This is due to the way in which DMX authenticates itself to the machine. When you upgrade to Windows 7, simply email in your new software ID and a valid registration will be returned for your new install. (Include any piece of information that would identify your purchase, such as your previous softwareID and Registration, the purchase transaction, etc. Usually your email is enough assuming you still use the same address as you did when you purchased)
