How can I update SDL Trados 2011 service pack 2 refresh??

I currently am using SDL Trados 2011, and it keeps telling me to update to it. BUT, when I log in My Account, it shows nothing. I am dying to update it since it's been 2 years for me to see this mesage!  I didn't buy the serial number, but I'm using my company's serial number for this program. Should I log in using another account??

Great thx for the help in advance :)
