Not working after update.

Hi,
Noticed that the feed stopped working after the post indexer update. So I went through the steps you described in the tutorial in installing.

First I replaced the file located here using ftp: http://yourdomain.com/wp-content/recent-global-posts-feed.php/

Then I removed all the old files in the plugin directory and put the new ones there.
And I can not access the feed.
Also there is conflicting information on where the feed is located. The plugin says: http://yoursite.com/feed/globalpostsfeed
Your tutorial says: http://yourdomain.com/wp-content/recent-global-posts-feed.php/

Neither of them work.

I also get this error when I tried to activate Recent Posts Feed Icon Widget:
Fatal error: Cannot redeclare class widget_recent_global_posts_feed in /home/5/b0029535/www/kostdemokrati.se/wp-content/plugins/recent-global-posts-widget/widget-recent-global-posts-feed.php on line 128

So please help me workout If I've done anything wrong. Need the feed working again as soon as possible.
