I have BT5R3 installed on a flash drive and the first day I used to to crack my WEP connection. Everything was working normally.

Now every time I try to do the same thing, during the "attacking" part it takes AGES to get packets. So long that I can't stand to watch it go up so I just leave. But when I come back the fern wifi cracker window is just gone. I assume that it just closes.

I've tried it a couple more times and the same thing happens. Extremely slow cracking speed and it just closes sometime in the process. Does anybody know whats going on?
