Crunch not working after installing cuda

[Nextria]

Hello,

I just installed cuda on my laptop with backtrack 5R1 32bit KDE, and everything seems to be ok.
But when i try crunch with pyrit, to bruteforce my .cap file, crunch just "hangs".

The command i use is:

./crunch 4 12 abcdefghijklmnopqrstuvwxyz | pyrit -r /root/capture-02.cap -e test -i - attack_passthrough

it did work for a couple of times, but now it just hangs on:

./crunch 6 12 abcdefghijklmnopqrstuvwxyz | pyrit -r /root/capture-02.cap -e ARV7519031D56 -i - attack_passthrough
Pyrit 0.4.1-dev (svn r308) (C) 2008-2011 Lukas Lueg http://pyrit.googlecode.com

Parsing file '/root/capture-02.cap' (1/1)...
Parsed 5 packets (5 802.11-packets), got 1 AP(s)

Picked AccessPoint 7c:4f:b5:03:1d:56 automatically...


and doesn't do anything else...


anyone got a idea what it could be ?!
