Trouble running CodeIgniter on a Windows server

[eluser]Matt D[/eluser]
Thanks for your reply. I picked a Windows server in case in the future I wanted to get into .NET development.

I turned on error reporting and it seems I found the problem. On the main page I got this "Fatal error: Call to a member function num_rows() on a non-object in D:\Hosting\9434915\html\ticketingdemo\system\libraries\Session.php on line 216"

I checked database.php in my config folder and it has the right settings. What else could cause this problem?
