Thanks, Matthew.
After I posted the above message, I visited another web site. When I came back to the DIS,I couldn't log in again! But I may have found a back way in. I click "forgot password", imput my e-mail address & when I get the e-mail with the links I choose the edit profile option. I get a message not logged in, but it does accept my password from that page. I hope this helps anybody else who is having the same problem
