PW-MIN - dont workin ??

[mastercracker]

First, because you did not specify an actual mask, oclhashcat default settings takes over. You have to add ?a?a?a?a?a?a?a?a to your command line (or an a better mask representing what you want). However, what is running on the image is length 8 with the first 3 characters masked (*) so --pw-min=8 does work.
