Original logon for XMarks was d_spisak@yahoo.com. I had to kill that account a couple of years ago when it was hacked. Now, just starting to use a computer for the first time in over a year. XMarks wants me to log on (to update I am guessing) but, because the yahoo account was "killed" it will not allow the logon. I need to contact SMarks to update to the email address of spisakbus@gmail.com but am unable to make any contact. HELP. As a result I am kept out of Firefox/internet.
