Stardock support are closed for the Holiday Season and will return to work on January 3rd. In the meantime you can try this to see if it solves your issue with the games.
Try closing Impulse and running the following file:
http://sd.stardock.com/curthendzell/fix_registrations.reg
Make sure to follow the link in Internet Explorer, as other web browsers will not handle the file type correctly. Once you follow the link, save the file and double click it to apply it. Then relaunch Impulse. You will need to re-login with your username/e-mail (either will work) and password.
Also. it makes it easier to track what has been tried and what help has been offered if you keep your post on the same subject matter to a single post.
If the above doesn't work then email support@stardock.com and start a trouble ticket. You only need to send 1 email to support as tickets are responded to in a first-in first-out basis. Multiple emails will force your ticket further back in the queue.
