When you create a new page, beneath the text box, there is a section where you can choose sidebar type (no sidebar, left sidebar, right sidebar). Be sure to select the appropriate sidebar type there.
Once you do that and create a new page, go to the widgets panel, and add the desired widgets into the sidebar which is named the same as your newly created page.
If you still have problems, send me your username and password of the WordPress admin so I can check it out. Be sure to mark the reply as private.
