Actually it's your WinCustomize subscription that lasts until September, 2008. Your Object Desktop subscription is valid until November 2008, however.
Are you not running WindowBlinds 6 or ThemeManager 2.50c? These are two release versions of applications newer than August.
As the SDC version you're running is outdated, I would suggest updating to a new version (it should find this through Tools->Check for application updates). If it doesn't recognize a newer version, I would suggest uninstalling Stardock Central, then downloading and installing the latest version from here: http://sdc.stardock.com/sdcentral_setup.exe
If you're still having a problem after this point, please send the login.txt file located within the C:\Program Files\Stardock\SDCentral folder along with an email referencing this thread to support @ stardock.com.
