Fatal Error: Site Tags

I'm using: WP 3.2.1 / multisite

I get "Fatal error" message with ONLY two plugins:
- Global Site Tags v 2.1
- Recent Global Post v 2.1

Warning: require_once(../wp-load.php) [function.require-once]: failed to open stream: No such file or directory in /mnt/stor1-wc2-dfw1/470380/www.greencubenetwork.org/web/content/wp-content/plugins/tag-feed/tag-feed.php on line 30

Fatal error: require_once() [function.require]: Failed opening required '../wp-load.php' (include_path='.:disappointed:usr/share/pear') in /mnt/stor1-wc2-dfw1/470380/www.greencubenetwork.org/web/content/wp-content/plugins/tag-feed/tag-feed.php on line 30


ALL other plugins work perfectly including:
- Global Site Search
- Post Indexer

I really need some assistance.
