BDP RSS Aggregator problem

I’ve installed BDP RSS aggregator in my wordpress 2.0. But when I’ve uploaded it to my website and I try to activate it, nothing happens and the screen goes blank and looks like theres nothing on it. In addition my whole blog does the same, so that nothing is showed at all. If I delete the BDP directory in my plugins directory it all goes back to normal. I tried all this on a freshly installed wordpress 2.0. What’s happening?
