Still does not work for me

I am trying on Workbench 3.1 (With BetterWB)
The ROM is 3.1
CPU is set to 68000 (Fastest Possible)
Chipset is Full ECS
RAM 2MB Chip and 8MB Z2 Fast
The WinUAE version I am using is 3.1.0
I get the same error as before. However if I use 68020 CPU it works.
Thanks, I'll try those steps out.
