Problem installing StagTools plugin on WP 3.6

I just installed the theme Geek Love which requires the plugin StagTools but I’m having trouble installing the plugin. This is what I get when I try:

object(WP_Error)#335 (2) { [“errors”]=> array(1) { [“plugins_api_failed”]=> array(1) { [0]=> string(218) “An unexpected error occurred. Something may be wrong with WordPress.org or this server’s configuration. If you continue to have problems, please try the support forums.” } } [“error_data”]=> array(1) { [“plugins_api_failed”]=> string(53) “Failed to connect to 66.155.40.249: Permission denied” } }
Something went wrong.

I am using FreeHostia for my hosting which has a MySQL version 5.1.50 and a PHP version 5.3 so I’m satisfying the minimum requirements of the plugin.

Any help would be really appreciated. I’m trying to set this up as my wedding website and am a beginner when it comes to WordPress.
