I'm trying to bruteforce a big list of MD5 hashes using Hashcat GUI and the OpenCL panel.
The options:

And when pressing start it opens cmd but does nothing:

I have no idea why.

you did not specify a mask, read this:

So if I want to use upper, lower and numbers I would have to enter: "i u d" in the mask area?
I'm using a ATI HD6950 btw.
EDIT:
That seem to have worked (?)
Although.

Hashes: 696015

I'm so, so sorry for not figuring it out. But I've tried everything in that article and placed it in the "mask" area of the GUI, but it gives me the same result over and over.
I'm new to this program so bare with me.

Mask attacks use literal characters ('i', ' ', 'u', ' ', 'd'), unless you use the special built-in variables (that are prefixed with '?'). BTW you want 'l' as in 'L' if you intend to use the built-in lowercase alpha characterset variable.

I would like to use uppercase, lowercase and numerals. Does that mean I have to put "l u d" in the mask area?
Anyway, I've tried it with just "l" but I just get the same result as above. Status exhausted and quits.

start with the following: put "?d?d?d?d?d?d?d?d" into the mask and try again

Looks right that time. However there was no 8 digits numbers in your hash list. You can check the box on the left of "Charset 1" and on the right side put ?l?u?d
Then put ?1?1?1?1?1?1?1?1 in the mask box.
