DIfficulties running mass attack

[alpaka]

Hi, I've tried to run mass attack like this

oclHashcat-plus64.exe -1 ABCD1234uyt dobry.hccap -o outp
ut.txt --increment ?1?1?1?1?1?1?1?1

WARNING: Hash 'dobry.hccap': Line-length exception
ERROR: No hashes loaded


but received error above.
I read Wiki and a couple of topics here so I don't know what am I doing wrong. Hccap was prepared by aircrack -J, I also tried converter on your site but got the same error.
Any help would be appreciated.
