It may be that the auto-login is failing. Two common causes of this are stale data stored in the registry (like if you changed your password or username) or if you purchased Elemental using a different e-mail address than the one currently associated with your Impulse account.
To determine the problem, please try this:
1) Create a shortcut to Elemental.exe
2) Right click on the shortcut and choose properties.
3) Click in the target field and hit END, then space.
4) Type /logxml then hit OK
This should cause files to appear in C:\ProgramData\Stardock\Elemental - War of Magic\ImpulseReactor. When you're done with the debugging, you'll want to turn this back off to avoid any possible performance hit from the files being written to the hard drive.
Look for files beginning with CVPLoginResponse. Open the file. If the ResponseMessage is not Success, the autologin is failing so it can't download the data files.
If the error is because the password is incorrect, (say perhaps because you changed your password) you can try overriding the values it's pulling from the registry by adding the command line parameters /username <username> and /password <password>, replacing the text in <> with your actual username and password. This will not save the values to the registry if they are succesful, but you can pull up the login dialog in game by hitting shift + Tab and then clicking on the settings tab.
If the error message is that you don't have access to this title, your Elemental serial is not associated with the account whose credentials are stored in the registry, and you will need to contact support. (This can happen if you bought Elemental using an e-mail not associated with your Impulse account.)
If the error message is something else or you need further help, please zip and e-mail the xml log files to me at carielf at stardock.com .
