CDaoDatabase: Office 97 -> Office XP - Cannot open database anymore!

I have a database that I access with DAO in VC++ 6.

CDaoDatabase m_dbDatabase;

I used to work with Office 97, but I recently installed Office XP, converted the database to Office XP format and now when I try to open the database:

m_dbDatabase.Open (...);

I get the following exception error:

Unrecognized database format 'c:\file.mdb'

I did get the latest version of the jet engine off the MS site, but still it does not work.

How can I get VC's DAO classes to open the new .mdb file? I thought this is all handled by the jet engine...
