I bought the EZSINO CSE-2007 package and I have just installed it on my computer. I have installed all the components as instructed. During the installation the username and password I received were USER19510 and JELDOT3L. When I try to log in with these, nothing happens. In addition, I cannot access the website www.ezsino.com and the email I sent to firstname.lastname@example.org was returned undelivered due to quota overflow. What should I do??
