Cannot import XML Demo content (Themeforest)

Hello folks,

I have just bought a Themeforest template -and installed it.

All went smooth until i was trying to import the demo content with the included XML.
For some reason it stops half way though… and does not look anything like the original demo 🙁

I have tried to research on similar issues, but cant seem to find the solution to my problem..
Some say its server rights.. so i tried cmod 777 the wp-content folder, but it doesn’t make difference.

I already posted on sellers forum for support but without an answer so far..

Here is a screenshot of where the process gets stuck..

XML (1mb):
Demo URL
My URL

So.. are here an expert who are willing to try and help me?
Really wanna get hands on and start modifying the template – i’m pretty stuck here..

Thanks in advance.
