hey james bond
try RAR password Cracker.. it will take you maybe days depending upon the no. of characters used.. but 100% guaranteed it will work ...
by the way how many characters is the password.. if its more than 6 then my dear it will take you more than 3 days i suppose.. but atleast if u know some of the characters like the first character or the last character.. then its possible for a faster crack...
u want the software then mail me..
or else
ENJOY
