I forgot to printout the confirmation, how can I get it back?

DV 2010 applicant's have the chance to check their status of their status after the month of July 2009. To do this they must have the confirmation number which was given to them after applying for the DV2010 by the E-DV application form. Once their application is accepted the computer screen will display the confirmation number along with the applicant’s full name. If you forgot to get it in a printout, "IT WILL NOT BE REISSUED AGAIN".
If you missed your confirmation number,
you can try it this way.(If your computer supports you.)
Stop the internet connection.
Open a new browser.
In the "File" click "Work Offline"
Click the history "history".
The list of web sites which you visited will appear
Find the confirmation web in the list.
You may find it.
Quickly write the confirmation number.
Then make a printout.
