I think you want to use oclHashcat-plus instead: http://hashcat.net/oclhashcat-plus/

Either download it from link above ^ , or if already done, move to the correct directory.

download hashcat-plus\ shift + right click anywhere\ open command windows here and..

cudahashcat-plus32.exe -a 3 -m 0 --force -1 ?l?u?d "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" ?1?1?1?1?1?1?1?1?1?1?1?1?1 -o unknow.txt
