Issue with Plugin Manager

Hi all,

I am trying to install some plugins. I think some issues will dissolve as I get others working but initially I need to get the plugin_manager working.  It gives this error: Cannot find parser for manifest API version 1.7 in plugin plugin_manager. 

I have version 14 of the plugin manager which has version 1.8 of the manifest.xml so why is it complaining about version 1.7?  Is something I'm missing making a call back to the wrong version? 

I opened my files in windows and copied them over via Filezilla.  I did check file permissions and everything checked out OK.  Any help would be greatly appreciated!!
