Well i recently followed the guide which teaches us how to boot bt3 without rebooting windows and stuff

So i installed linuxpendrive and did everything accordingly. But linux does not detect any cards due to which i cant even do the first part of cracking wep
Furthermore whenever bt3 starts it comes up with this error

''Error KDesktop
The process for the file protocol died unexpectedly''

Can someone please assist me with this problem i'll really appreciate it. Its almost been a month now that I'm trying to sort out BT3 but something or the other always turns out 2 be a pain in the backside!!
