Digital River unable to find filr 3/3 on the server

Thanks for the feedback. Do tell if it worked or not! :)

Ok, here is an update on my part:

The same day I made this topic (the day I bought win7) I wrote a mail to Microsoft about the download problems and also noted that I have reinstalled Vista in order to eliminate all possible problems (which indeed I have).
Yesterday I got an email from the support, saying that they will refund my 35€*that I payed for the Win7. Furthermore they allowed me to keep my win7 license for free and they also provided a link to try and download Win7 again.
I tried downloading Win7 this morning via findmyorder.com and it worked, I now have all files needed for the installation.

Now all I need to make is bootable copy out of it, as I want to install 64bit system (currently I have 32bit Vista).

Bottom line is: I had download problems > I wrote an email about the situation > I got my money back and they let me keep the license for free.
