I have twice now waited 24 hours for Impulse to send me an email to reset my password so I can download the patch and expansions for Sins of a Solar Empire.
It never arrives, but I have recieved the emails from the support people from Impulse and other websites usually only take 10 minutes or less to retrieve account information through an email.
This is very frustrating, and all the support people say is; 'wait 24 hours, or we can send it again but that will reset the timer'.
I've waited 24 hours twice now. No email.
