Upload Themeforest Gspa Demo to Wordpress - Help needed

How do I upload the Demo for the Gspa Themeforest theme to wordpress?

I am new to this and would like some very specific and clear instructions

I uploaded the xml file - can u guide me to the correct one
I added a widget uploader to WP
I can only find demo content in the cache/demos folder called 1.wie
I uploaded but does not give the same as the demo page I bought?

thanks so much!
