Hey guys, I found some old recovery CDs of mine, which I unfortunately rared with winrar 3.

Ok, after I'm done with the disclaimer:
How do I retrieve the password? I found a program that was able to utilize the GPU instead of the CPU, so instead of 800 passwords a second (with my 4x3.00GHz Athlon), it managed to achieve 3100 passwords/s.

Sadly it does not support 6xxx ATI's only up to 5xxx ATI Sad

Any idea? (it should work with my 6950)

Thx, seems as if I had the old version of that one! And what a difference... My 4850 managed 3200pw/s.

It's at 12000pw/s with my 6950 :O

Nope, just did a test run with the trial. I'm not sure if the trial version will return a password though. And there is no cracked version of the app. Well well...

@leo: I'm not sure, but northern island was not supported Sad
