Fatal error if packets enabled

I downloaded vshare yesterday and installed it today. It is working, but after I switch "service type" to "packets enabled", it will not work anymore and I'll get this error message: "Fatal error: Call to a member function on a non-object in /home/videotwi/public_html/ee/index.php on line 113"

Could somebody explain me what is wrong please?

If you can PM me your web site ftp, cpanel and vshare admin login details, i can check it for you. Include reference to this post when you PM the details.

That's strange, after I deleted cache and cookies, this problem disappeared.
