I have the same problem as David Schapira.
When I fire up Stardock Central, it comes up with a "Create Stardock Net" account. I fill in everything, click submit, and instantaneously it says, "Fails to Update Account Information". There is no sign of anything having gone over the net. If I "skip", I get a complaint that without logging in, I can't do anything.
If I then "skip", I get to the main Stardock Central page. If I go to Tools/Register Products and enter my serial number (for GC, not Drengin.Net) when I hit OK, I get an hourglass which stays on the screen for as many minutes as I care to watch. This is true for both Atlanta and California servers.
Reinstalling SDC doesn't wipe the component keys, but if I do it by hand and reinstall, nothing changes.
Can anyone help me?
