I use GOGDownloader (version 0.9.0.1376) to download my games. Usually I click on the game on my shelf, then click on "Add to GOG.com downloader", and then on "Add game to downloader". Then the link is sent to the GOGDownloader, which then manages the download.
Or so it worked until some days ago. Because now, when I click on "Add game to downloader", I get a message "No registered application for this extension". This is odd because in Opera's preferences, the extension "gogdownloader" is correctly associated with the GOGDownloader program. Also, downloads started from Firefox work just as well as before.
Any ideas what could be causing this and how to fix it? I'm using Opera 11.60 (recently upgraded). Thanks in advance!
