Problem with Dwg. changes and updates not printing after saving.

I am using the Free Draft Site version to do simple 2D drawings.  So far I have been able to successfully make drawings and update or make changes.  Just recently, I made changes to a drawing and printed it.  The changes show on my screen, and I save them.  When I print the drawing the latest changes do not appear.  I use Ctl+S to save them and have used the save window, both.  Still the changes do not print.   The first few times I did drawings and made changes, everything printed OK.  Now, I can't get changes to print, only the original drawing.   Need Help!!
