I assume you are using the correct URL (http://192.168.0.1/)? Are the power and ethernet adapter lights blinking?
Tough to diagnose without seeing the unit, but assuming you have the correct wall-wort (Volts/milliamps), lights are blinking, your hard-lined with an ethernet cable that works, and your using the correct URL, it should work.
Sorry can't be more help. My understanding is that the fellow that built the original BCS (now sold through Brewer's Hardware) stands by his product. Worst case, you could contact them and see if they'd be willing to have a look.
