Username/Password is wrong-error code:8007052e

Hi,
we haven't got around to changing the default username and password from the system default.  We can get into the application but can't run reports.  This is the built-in admin account and preset password.  We can still see the text on the logon page stating ' Note:This box will disappear once you change the admin password.Default password is "admin". So we are certain that we are still using the system username and password to log in.  I have tried resetting the password, using 'admin' as the old one, but this doesn't work.  I am told that my 'old password' is incorrect.
Have you any ideas?
K.
