Bookmarks missing

[dbisigna]

Bookmarks there yesterday and gone today.  Instead of the bookmarks bar, it's asking me if I would like to import.  when I click on bookmarks, there is nothing there. However, when I looked at C:\Users\dsb\AppData\Local\AVAST Software\Browser\User Data\Default, there they still were(Bookmarks and Bookmarks.bak).  Any suggestions on how to get the Avast browser to open them?

UPDATE:  As closing the browser and reopening it did not work, I reinstalled it without first uninstalling it.  It opened back up with the bookmarks back where they should be.
