You can also look into Windows own "recent versions" option. From your home directory type in 'AppData' in the address bar which gets you into AppData (normally a hidden directory). Continue onto Roaming and 'Opera Software'. You should now see the Opera folder. Right click on it, check it's properties. You should have a "Recent versions" tab there, chances are high that it will allow you to open a previous version of the folder which could have backup copies of your files.
