PacketFu troubles

hello,

I’ve got a lot of trouble with PacketFu (from
Google Code Archive - Long-term storage for Google Code Project Hosting.).All I wanted to do was a bit of network
sniffing but everytime I want to use packetfu I get this message:

I got Winpcap(version 4.0.2) installed and can sniff with wireshark
without problems.

Now I’d like to know why it isn’t working and how to fix it(is this
problem winXP specific, a common problem on windows ?)

if anyone has experienced similiar problem( and found a solution) please
tell me

thanks in advance
