c# i access baza

Baza je encryptovana sifrom.Kada uradim ovako nesto kaze mi da mi sifra nije u redu:

OleDbConnection konekcija = new OleDbConnection(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Users\Gaja\Documents\Database1.accdb;Persist Security Info=True");
OleDbDataAdapter adapter = new OleDbDataAdapter("select dsfg from table1", konekcija);
DataSet dataset = new DataSet();
adapter.Fill(dataset,"table1"); -----not a valid password
Kako da resim ovaj problem?
