Icodes import plugin

Hi,
I tried to install Icodes import plugin by “Theme Options” ==>”Extra PLugins” ==>”Import Tools” ==> “Icodes Import Plugin (Version 1.0) – Updated August 24, 2013”, I got the following error:

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.

I also search wordpress.org for the Icodes plugin, but I can not find anything.

Now I use Coupon theme 4.4 in my local machine(localhost).

Please advise where to get this plugin.

If I want to upgrade to coupon theme 4.5, would just copying the theme files enough? Or I need to do the whole re-installation?

Thanks
