CDJ and CCF

Help please.

I've been absolutely delighted with Slinke/CDJ and potentially Pronto & CDJ2CCF look great. Provided I can solve this problem......

I'm having great difficulty making a .ccf file from my CDJ database. For reasons I don't understand, my players "1" and "2" appear in my .mdb file as "0" and "1". Any discs in the database, but not in either player, ie "?" in CDJ, appear in the .mdb file as "-1". This appears to generate a "subscript out of range" error in CDJ2CCF and prevent the creation of the .ccf file.

If I remove the "?" items the .ccf file emerges, but items from the exception database are not included. The "player" and "location" columns in the exception database are all "-1". Is this right? And why aren't players "?","1"&"2" in CDJ simply "0","1"&"2" in the .mdb file? Any ideas gratefully received.
