Ties your using v4 not v5 as looks like your using CE database.
Regardless of what you issue if I would look to love to SQL either as localDB or full SQL Express

thank you . today i change ready now using sql server instead and working with no issue

Yes you should avoid CE at all cost it is horrible. Maybe Emre will retire CE for good with v6.
