You could go to Modelspace and click on "Named View" to open the "View" palette. Click in the "Active" column for one of your saved views to take you to that view. If it's not where it is supposed to be, you'll have re-create the view. Once you get the view situated correctly, select the Name in the View Palette, then click on the "Update" button in the palette toolbar. Back in Paperspace, you'll probably have to select the Viewport and re-select that view from the View Name list to update it.
