You're in luck... 
I replicated the issue. I can't upload a photo as I have no way to scale down a jpeg file to 97KB on my phone.
Solution:
Move the ACATune line to just above the 'C:GetMouseInput LOCAL'. So it'll look like this:
;ClassicWB Startup-Sequence
;--------------------------------
;LITE 3.1
IF EXISTS DEVS:scsi.device
C:LoadModule DEVS:scsi.device
EndIf
C:ACATune -cache on -burst on -vbrmove -maprom * p >ram:acaoutput.txt
C:GetMouseInput LOCAL
IF $MouseInput EQ 1
...
It turns out that LoadModule doesn't appear to work if run after ACATune in this particular configuration, even if no extra options are added such as maprom. ACATune with no further options simply adds extra memory...but LoadModule doesn't appear to work with it in this way. But this makes sense really... Here we have an ACA1232/1233 that under Kickstart 3.0 doesn't configure all of its extra ram - it only configures 1MB. So after the ACATune command is run, followed by the LoadModule command, the machine resets and because we're running Kickstart 3.0 here the ram is lost and the Amiga configures 1MB again. This then appears to leave us with a black screen, although I was able to hold both mouse buttons down and boot with no startup-sequence and confirmed that the scsi.device was at 37.64 (standard with Kickstart 3.0). Of course, if the LoadModule command had worked then it would have been of a higher level.
There's no real reason for you to upgrade to Kickstart 3.1, but like I said earlier, you can use the ACATune command to softkick 3.1 and if you were to do this then remember to put the ACATune command line back to where it was - before LoadModule.
Also, what capacity is your CF Hard Drive? If it's 4GB which I suspect it is then the scsi.device shouldn't even be there on disk, and you could simply comment out the LoadModule line for a quick fix. If it is only 4GB, then the person who configured your setup has made an error which has cost us both a lot of time (ClassicWB by default doesn't use an upgraded disk based scsi.device, although it is optional).
Let me know how it goes...
Your an absolute star. I can't thank you enough. Its working now; I'm getting tons of other mem.Two soft resets and a hard reset and the other mem is still there.
Now that's more like it! It would have been a shame not to get the most out of my aca card.
The cfcard is 8 gigabytes btw.
It says in the readme that the aca can be used to simulate other system configs, i.e. a 1 meg amiga etc. I noticed some games for example apano sin don't run. Perhaps it requires a specific system set-up?
Anyhow; i guess I could use the acatune floppy to change the config as I needed it, to run a specific game? The setting would be erased upon powering the amiga off anyhow, I guess; and so the acatune startup line as we have it now would remain untouched?
Again thanks very much. And thanks to oldsmobile mike too.
I'll get myself a cd drive soon and then have a crack at setting up this easynet wireless thingy.
