Un-install everything relating to Stardock on your computer. www.stardock.com/sdnet_login.asp (cut and paste in your browser) download and install Stardock Central. Put CD in drawer for save keeping. Register serial #'s in SDC in lower right and install everything from there. If you want the beta's (and you do) then check 'Show Pre-release Versions' in lower left. Do one at a time and try loading it so you know which one, if any, is giving you grief. Let us know if you get it up and running or if you're still having problems...
