I too have had this problem. I just signed up on the 19th by paying with paypal. I cannot access my account. It's saying Error! Username or password is incorrect. I tried the "forgot password" option to see if it can send me my password. I have not received any email from dreamhost. It's not in my spam nor my inbox. I've tried this several times.
The domain that I signed up with is gamingheavens.com.
My friend uses this hosting company for his website, he said setup was instant. So how can I get access?
