My Dell Downloads

Good day.

Few weeks ago I have received Dell Studio 1749. In order to install better Microsoft Windows version I have formated my hard drive. Now I have no programs because Dell doesn't include most of them in the program DVD. I have tried to register my system in My Dell downloads but that failed, it was said that my Service Tag is invaild. But that doesn't end here - today I cannot even open My Dell Downloads page, I am prompted with an error "An Application error has occurred. Please contact customer support if this problem persists". I tried to open that page on different computer and everything worked fine...

Could anybody suggest anything to solve this problem? My shipment date was 30th of July so that's really enough time for Dell to add my Service Tag to their database and I am using Windows Explorer with .NET Framework 4 as suggested in the FAQ.

Thank you for the help.
