I have the following 2 problems with hashcat 3.0 and 3.1:

after having installed a new nvida-Driver (372.54) for my GTX750Ti I launched a 7zip test decryption.

The password was "яliebeтебя" (special for this forum thought out password).

I launched a dictionary attack. The dictionary contains only this word. I created 2 dictionaries: Win1252 and UTF8. Both attacks were unsuccessful.

Code:

hashcat (v3.10) starting...

OK. Then I changed the password in "ichliebedich". Created a new dictionary with this word and launched the attack again.

Now getting the error message: ERROR: clEnqueueReadBuffer(): CL_INVALID_VALUE

Why did I suddenly this error? I have not changed the system (i7-6700 3,40 Ghz, Asus GTX750Ti, Win10 64bit German Home with anniversary update, hashcat 3.x 32/64).
