problem with PHPShop 1.2 RC1 for Mambo 4.5.1

[bgdeveloper]

Hi,
I've installed PHPShop on Mambo 4.5.1 and when I try to emable the downloadable products and open the front page the Shop menu breaks after the first category. I give \"View Source\" and the HTML is just cutted from that position to the end. I've uninstalled and installed it again and when I enable the downloadable products it fails again

Do you have any idea where can be the problem?

Configuration -> Downloads-> \"Enable Downloads\"
