Can you confirm if RawWBInfo is running? IIRC it is a commodity, so it should show up in Exchange.
If you can't find an obvious reason for it not working, despite being in the WBStartup etc., a good way to spot many problems is to try SnoopDOS. In this instance, take RAWBInfo out of wbstartup and run it after starting SnoopDOS.
Any failed libraries/classes/whatever should be duly reported.
