Recordset error Unrecognized database format

I am working with a recordset problem in Access 2010. Below is the code I have so far and I get an error where commented. The error I get is: Run-time error '-2147467259(80004005)':Unrecognized database format 'C:\Users\fc\desktop\MyRecordsetDB.accdb'.

I have the following References active:

Visual Basic for Applications

Microsoft Access 14.0 Object Library

OLE Automation

Microsoft ActiveX Data Objects 2.6 Library

The database was created using Access 2010.

I have not been able to check any of the rest of the code so I don't know if there are any other errors.

Code:

Private Sub Form_Load()

Dim cnn1 As ADODB.Connection

Dim rs As ADODB.Recordset

Dim strCnn As String

'create string var to hold new information

Dim strID As String, strLot As String, strAM As String, strPM As String

'variable to hold path to current db  name

Dim strPath As String

strPath = Application.CurrentProject.Path & "" & Application.CurrentProject.Name

Dim mydb As String

mydb = strPath

'MsgBox strPath  for testing purposes only but shows correct path

' Open a connection.

    Set cnn1 = New ADODB.Connection

    strCnn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & mydb

    /////////////Error occurs on next line/////////////////////////////

    cnn1.Open strCnn

' Open contact table.

    Set rs = New ADODB.Recordset

    rs.CursorType = adOpenKeyset

    rs.LockType = adLockOptimistic

    rs.Open Source:="Select * from tblTest"

'get the new record data

        'Use inputbox to get info for new record

        strID = Val(InputBox("Enter ID", "Manager ID Number"))

        strLot = InputBox("Enter lot number", "Lot Number")

        strAM = InputBox("Does this employee work the AM shift? vbnewLine Enter Yes or No", "Shift Assignment")

        strPM = InputBox("Does this employee work the PM shift? vbnewLine Enter Yes or N0", "Shift Assignment")

        rs.AddNew

        rs!mgrID = strID

        rs!mgrID = strLot

        rs!mgrID = strAM   'update the Y/N field in the recordset to Yes or No

        rs!mgrID = strPM   'update the Y/N field in the recordset to Yes or No

' Show the newly added data.

        MsgBox "New manager ID: " & rs!mgrID & " has been successfully added"

'close connections

    rs.Close

    cnn1.Close

End Sub

Thank you for your help
