Have you contacted your hosting provider to check your server download speed and if the server can programmatically connect to http://templates.themepunch.com ?
Try to increase PHP time limit to 60-80. Also, provide us the list of the server error logs.
P.S. We have imported slide by slide manually, so you can find fashion slider in the list of sliders. We suppose that problem with import of the whole slider is related to your server and PHP time limit. So, contact your hosting provider to solve the issue for future.
