Access and PsqLODBC

I have been getting an error.  I have a Microsoft Access 97 database with some tables linked to a postgresql 6.5
databaseon a linux server.  Sometimes while inserting into the database (happens in different places on all tables).  I
haveversion 6.50.00.00 of the ODBC driver.  
 

In the driver button on the configure for the ODBC I have checked (Disable genetic Optimizer, KSQO,Read Only) 
Unknown Sizes: Maximum
Data Type Options: Text as LongVarChar, bools as char
Cache Size: 100
Max Varchar: 254
Max LongVarchar: 8190
SysTable Prefixes: dd_;

In the DataSource Button The only thing selected is Protocol 6.5/6.4

This is the sql to create the table
CREATE TABLE TBL_Ads (  AdID           serial,  Company         varchar(254),  ContactName     varchar(254),
ContactPhone   varchar(254),  ContactEmail    varchar(254),  AdType         varchar(254),  SiteLocation
varchar(254), StartDate       date,  EndDate         date,  WebSite         varchar(254),  AdImageUrl     varchar(254),
Keywords        varchar(254),  Category        varchar(254),  RecordID        int4,  Enabled         bool,  Psa
   bool,  Filler          bool,  target          varchar(30),  ban             varchar(254)
 

);

create index tbl_ads_addtype on tbl_ads (adtype);

create index tbl_ads_sitelocation on tbl_ads (sitelocation);

create index tbl_ads_keywords on tbl_ads (keywords);

create index tbl_ads_startdate on tbl_ads (startdate);

create index tbl_ads_enddate on tbl_ads (enddate);



The only difference between these when I entered them was, I entered 5/5/2000 for the start date in the ones that were
deleted. If you have seen this before or can shed any light on it I would appreciate it.
