I did not succed either! 1) Newsplorer seems to work also on Vista, although on their home page, they don't say so: "Platforms supported: Windows 95/98/ME/2000/XP/NT" Source: http://www.newsplorer.com/index.php 2) I tried to install 2 AB feeds on Vista and XP and it did not work for me either. So Vista is not the problem. 3) What follows is how you could install a new RSS feed on Newsplorer (but it does not work for AB, as far as I can see). (I assume Newsplorer is installed and working): Assuming you want to have the answers to your questions. - open your private profile: http://www.answerbag.com/profile/ - in the right rand, under my points and my ratings, there is an orange "RSS" button. Click the "Get new answers to my questions." link under it. - in my case (or if you want to get the ansers to my questions), you come on the page: http://www.answerbag.com/rss/about?t=1&id=147540 - copy the feed address to the clipboard - with CTLR+C or with the context menu (right mouse key) - right click on the Newsplorer icon on the Taskbar (at the left of the system time display) - in the popup, click Configure - in the Newsplorer configurator, left margin, click "News Feeds" - click the button "Import OPML" at the bottom - in the field "Enter the location of the OPML resource", paste the content of the clipboard: http://www.answerbag.com/rss/userrss?t=1&id=147540 - click the "OK" button. (this point seems not to work very good: you often get a time out error) If it works, you get a new window where on the left side, the feeds should be listed. No feed appears here. Remark: the possibility with "del.icio.us" is the same, just your subscripted feeds configuration is stored online. In this case, you need a Bloglines.com account and a password. 4) I had a look at their forum: http://www.newsplorer.com/forum/index.php (or click "Forum" on their main page) I noticed that the last post on the Forum was on September 23, 2006. So no much activity there... Under "Discussions/General Discussion" there is a posting "problems with newsplorer". Two users had problems, one of them because that was an XML feed. The moderator gave this answer: "The reason is that the XML does not respect the RSS 2.0 specification. Other readers are more permissive from this standpoint..." So this could be the problem: this reader is "not so permissive". By the way, the second user had problems with RSS that should have work. But they did not answer the moderator request for details, so we shall never know...
