I am trying to configure SSABI. SSABI is halting with an error.

The system config:
Windows Server 2000
SQL 2000 SP3
MSOLAP - Analysis Server SP3
Office XP SP1
And the latest BI accelerator.

When I try to process the Retail Analytics model, I get an error
Error: Invalid procedure call or argument
Location: Create_Olap_Dtb
Analytics Builder processing halted unexpectedly.

BI halts, without processing the Cubes, and the MDDB is not created. Any help would be appreciated.
