i just installed the latest and greatest version from scratch on a new site and install was successful and I can go to the Admin section but when going to the store I get this errror:

Fatal error: Cannot instantiate non-existent class: cart in /home/wwwpos/public_html/includes/boxes/shoppingCart.inc.php on line 42


Any ideas? i tried reuploading that particular file but no success.

here is another when i tried to add a product
Fatal error: Call to undefined function: imagecreatefromjpeg() in /home/wwwpos/public_html/classes/gd.inc.php on line 49
