Opening access 07 databse in excel 07

[ck1999]

I am trying the following code:

Dim newdb As Database, newws As Workspace, suppliers As Recordset, tradenames As Recordset

Set newws = DBEngine.Workspaces(0)
Set newdb = newws.OpenDatabase(Db2Name, False, True)
Dim newtable As TableDef

I get an error "unrecognized database format".

I have Microsoft DAO 3.6 referenced
File in not password protected

which will work until I upgrade to office 07. Any comments or Ideas of what is different?
