It has been so long since I set it up I cannot remember, I do have a user name and password wrote down but neither of them work, I thought my user name would be my email address?? I thought there may be somewhere I could ask within windows by asking other security questions.
You probably don't need to access it for now. But you should know your password. Your username can be found in the email account settings and may well be your email address. SIW may find your password.
" but I still have no idea how I can retrieve my user name/password"
See my post at 7:24PM. You could also use the Eureka! tool. In SIW click on the Magnifying Glass to open the tool then open Windows Mail, Accounts and properties for your email account, go to the tab where it has your username and password. The password will be a row of large dots, drag the magnifying glass over the row of dots and the password will be shown in Eureka! in the bottom text line box.
I note you had same problem in July 2010 and again in Oct 2011 and we gave about the same advice then. Did/are you having problems using SIW to find your Virgin email username and password? (I presume you are still using Virgin email)
