Problem getting contacts from Exchange

When I attempt to use ADO to get data from any "Contacts" folder I always get...

System.AccessViolationException was unhandled
Message="Attempted to read or write protected memory. This is often an indication that other memory is corrupt."
Source="System.Data"

string connect = @."Provider=Microsoft.Jet.OLEDB.4.0;Exchange 4.0;MAPILEVEL=Public Folders|All Public\Our Contact List;DATABASE=C:\\Temp\\;";

OleDbConnection connection = new OleDbConnection(connect);

connection.Open();

OleDbCommand command = new OleDbCommand("Select * from [Staff]",connection);

using (OleDbDataReader dataReader = command.ExecuteReader(CommandBehavior.CloseConnection)) // EXCEPTION HERE

{

while (dataReader.Read())

{

System.Diagnostics.Debug.WriteLine(dataReader[0]);

}

}

I've tried the same code against my local stores and I get the same result. However, it works fine for every other folder type, Tasks, notes, inbox, etc. Any ideas?
