[Plugin: BloggerSync] Great, NOW its broken

BloggerSync was working fine up until I did the latest BloggerSync update and got Zend errors anytime I tried to post. So I thought I would uninstall and reinstall the addon to clear it. Well, now it wont even reinstall due to Zend errors:

Plugin could not be activated because it triggered a fatal error.

Warning: require_once(Zend/Validate/Abstract.php) [function.require-once]: failed to open stream: No such file or directory in /home/content/72/6434772/html/wp-content/plugins/bloggersync/Zend/Validate/Hostname.php on line 25

Fatal error: require_once() [function.require]: Failed opening required ‘Zend/Validate/Abstract.php’ (include_path=’.:/usr/local/php5/lib/php’) in /home/content/72/6434772/html/wp-content/plugins/bloggersync/Zend/Validate/Hostname.php on line 25

I don’t know anything about coding but I did check my directories and those files are there. Also, I don’t remember what error I was getting before I uninstalled the addon. I tried going back to the older version but it too now gives me the same error. Please assist.
