I agree, the same database for both, however - did you click on the TOOLS on the top line of Sentinel and change the TARGET MODEL to BCDx36HP?
That might be required to get it to write the database to your scanner. After changing the target type, then do the write to scanner. Also note my above message about Sentinel not knowing what you might have written to the scanner using PROSCAN.
I don't think that will make a difference with the database... But it wont hurt to try it...
