Some answers:

1. DownloadStudio stores all your download history in the users application data folder in the subfolder "Conceiva\DownloadStudio". The folder location will change depending on what operating system you are running:
   
   C:\Users\<username>\AppData\Local\Conceiva\Downloa dStudio (for Win8/Win7/Vista)
   C:\Documents and Settings\<username>\Local Settings\Application Data\Conceiva\DownloadStudio (for Win XP)
   
   Make sure you have exited DownloadStudio before making a backup of this folder.
   
2. Opera has changed their extension/add-on system so the DownloadStudio extension will no longer work in Opera 23+. You must use a previous version of Opera to integrate DownloadStudio or use the latest versions of Chrome, Firefox or Internet Explorer.
