cudahashcat error

[realf*ckinghigh]

thanks for the reply, but the problem is not the username switch.

I can remove it, and edit the hash obtained from office2john, but get the same error. The same command runs fine on a different machine, but its graphics card is rubbish so its not worth trying.

I am also trying with a dictionary, but i want to see how long brute force takes too... so not really uneducated
