Your password should be atleast 8 characters long and contain a capital letter and a number. Does that help you remember?
If not you can reset your password and choose another one by going to the login page and clicking on 'I have forgotten my password'. Type in your email address and click submit and the software will send you a temporary password that you will have to change when you first log in.
WHEN USING THE TEMPORARY PASSWORD WE STRONGLY RECOMMEND YOU COPY AND PASTE IT.
