Maybe somebody will learn something from my experince ..
I loged again to my account with digital river .. and place new order
(finally win 7 pro) was an available option ..
after 30 min I get the confirmation email ... with product key
The most important thing .. is
I used the product key that I received as (Any time upgrade) key ..
And Woow .. it works perfectly and after 10 min's, I am using Win pro 7 !! no data lost .. no backup ..
That's true I paid $39 CAD twice, but I opened a ticket with digital and requesting refund ..
The bottom line as .. even with product key .. you can use this key as any time upgrade .. at least this works perfectly with me ...
Thanks for every body for your help ...
