This free utility will allow you to at least see your passwords.
If it doesn't find the passwords automatically (in my case it displays my Google Chrome ones by default not my Opera ones) select "Advanced Options" under the file menu, check the "use the following profile folder" box and enter the path to the Data folder of your Opera profile.
You can see where that is under "About Opera" in the Opera main menu.
It will be something like C:{user path}\Opera\Profile\Data.
HTH.
