Apols for double posting - under pressure :-)

Hi All, I need to update some Fox tables from SQL Server 2000, here's what I've tried without success

update openrowset
('vfpoledb.1','\\pjkserver\data\apps\app1\data';'';'','Select active from mytable where pkref = "E10295"') 
Set active = 0

I receive the error

Server: Msg 7301, Level 16, State 2, Line 1
Could not obtain a required interface from OLE DB provider 'vfpoledb.1'.
OLE DB error trace [OLE/DB Provider 'vfpoledb.1' IRowsetChange::QueryInterface returned 0x80004002:  IRowsetChange].

If I just execute the Select part it works fine - I have the latest VFPOleDB driver and am running XP pro Service Pack 2, any ideas ?
