DV Lottery 2009 Special Case

Hi,
Two weeks ago I received a notification letter from the KCC for the DV Lottery 2009. I am currently filling out the forms included in the letter and trying to send them back by moday. The problem is that I have been in the US already. I eneterd the country legally on a visitors visa, extendet it twice and then after being accepted into a college I applyed for a change of status but was denied. After that I satyed in the country illegally for over a year and them came back to Europe volunteerly. While in the US I did not have any criminal records, no SSN, no ID's, no driving license, no bank accounts, no address registrations. When I was leaving at the airport they did not get my I-94 form becasu my passport had previously expired and I had already change it. The problem is that now when I am filling out the DS-230 form on the part where they ask if I have overstayed in the country illegaly over a year do I put YES or NO. Do they have any evidence that I have overstayed for that period. Also in the part where they ask bout all your previous addresses since the age of 16 do I write down the addresses in the US when I have been there illegaly or I just skip them.
Thanks a lot!
