I recently was upgraded to NIS 2011 but inserted my 2010 CD to verify the code number and it tried to load the older version from the CD. I canceled the 2010 CD older installation and yet everytime I boot my computer the installation screen appears instructing me to insert the CD to complete the installation. 2011 is running fine, but the 2010 window that appears everytime I log on is getting annoying. How do I stop it?
