JInstaller: :Install: Cannot find XML setup file

Hi,
I have just bought lifetime membership from you guys and the awesome templates. But at the very first time I am finding error(unfortunately)! Can you please help me into this? I have installed Joomla using my Hostgator CPanel and then tried to install your Pixellove template. So fat it was all fine, but when I tried to install to "gk_pixellove_rest_files_J!16" for all the cool features, its returns with an error! Hammm, this is my first time with an website building. Sorry if its a lame mistake...

P.S: Screenshot attached.

Hi, rest_of_files - unzip this before and you'll see there are folders with:
1) PSD files not for installation only for photoshop
2) and plugins - those can be installed one by one

Hey,
Is that mean I just have to install all the .zip files from the plugins folder and that's it? Don't have to create any modules or nothing for the other Gavick component to work properly For Eg. "News Show Pro GK4"? I just read somewhere in your forum that I have to do that too...
