Cannot enable module due to error with Zend

I've uploaded the video_upload module and the Zend library folder into the same video_upload folder but when trying to enable the module it gives the following error:

 * warning: include_once(Zend/Loader.php) [function.include-once]: failed to open stream: No such file or directory in /home/galeads/public_html/dev/modules/video_upload/providers/youtube/zend_gdata.inc on line 225.

    * warning: include_once() [function.include]: Failed opening 'Zend/Loader.php' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php:modules/video_upload/providers/youtube') in /home/galeads/public_html/dev/modules/video_upload/providers/youtube/zend_gdata.inc on line 225.

    * The Zend Client library loader is required by the Video Upload module, and has not been found. This is a strong indication that the required Zend Gdata libraries are not installed. These can be downloaded here.

      Information on installing the required library can be found here. (Currently using Zend Loader Not found)

Any help on this at all? I've verified that the files are in the correct place, but still no luck. Is there a particular version of Zend needed? I've used 1.5.1 as well as the newest release 1.7.1.

Thanks in advance for anyone's help with this!
