Couple of misconceptions:
You don't set the D8B up as a controller in Logic AT ALL, if you're using it as a mixer, only.
Having said that, it's possible to switch faders 17-24 to HUI mode from the D8B hardware (look in the manual). If you want to use that, then, sure - you have to add a HUI in the Control Surfaces area in Logic, and select the MIDI input and output ports that go between the D8B rack unit and your computer MIDI interface.
BUT... if you intend to use the ProBox with an external switch, you probably want to skip the HUI setup above. When using the D8B with the ProBox, you should switch the ProBox to Logic Mode (see manual), and then add a "Mackie Control Universal" unit and set it to the ProBox MIDI port 4. Then add a Mackie Control Extender and set it to ProBox MIDI port 3 (place to the left of the MCU unit in Logic), then add ANOTHER Mackie Control Extender unit and set it to ProBox MIDI port 2 (place it all the way to the left of the other two units you just created in Logic).
The result should be, that the D8B (with a ProBox connected and active via an external switch), would act like a Mackie Control unit with 2 extenders.
Yes, there are two different cracks. Bruce was referring to the "older" crack (.asc replacement), that I had linked to, but Angelo shared a link to the newer crack (.exe replacement), and that's where the confusion came in.
You installed the newer/exe crack, so there's no .asc file to replace. You replaced the .exe, and that's it. (No plug-in authorization codes needed, from what I read about the newer crack... I've had everything authorized with the old method for a long time, so I don't know from personal experience).
OK... to briefly touch on what Angelo already explained: So, you connected some ADAT optical cables. Did you set up the Wordclock sync, yet? Do you have an Apogee Clock card, or is there a slot-cover over the "clock" slot in the back of your desk?
If you have an Apogee Clock card, you can use the desk as both, Word Clock Master, or Word Clock Slave. If there's a slot-cover over the "clock" slot, then you can only run the desk as Word Clock Master (and not as Slave).
ADAT only is not enough to sync the D8B to your audio interface's word clock (again, as Angelo said). You NEED to have a BNC word clock cable connected, to sync the D8B to anything other than it's own clock.
Anyway... Angelo is already helping you out with the clocking and routing, anyway, so good luck with that!
...and exploring and figuring things out by myself, was half the fun, when I first got into audio back then... maybe just try a few things, sometimes, and see if it works...?
You know how to route audio out of the ADAT ports on your audio interface in Logic, though, right? If not, I'm sure there are youtube videos.
