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.
hi!
i had already tried that, but it didnt fix the problem. but now the problem kind of fixed itself. when i started impulse yesterday, trine suddenly showed up as available in my games-list (and also in the register-product-dropdown-menu).
but thanks for your help anyway!
