Connection to Access error

[Bruce007]

I am using VS2013 VB and have created several routines. The library project connects to Access (mdb and acceb) just fine. When I move the class to another project I get an error that it can not connect. Why?

My code it:
Public Function Open_Access(ByVal dbname As String, Optional ByVal usrname As String = "", Optional ByVal pwd As String = "", Optional accdbflg As Boolean = False) As Boolean
Dim sConnectString As String
Dim i As Integer

On Error GoTo ERR1

Open_Access = False ' default to failure
AccessDatabaseOpenFlag = False

If dbname = "" Then
Call Display_Message("Access database name not provided.")
Exit Function
End If
If File_Exists(dbname) = False Then ' if no such DB
Call Display_Message("Unable to locate Access database.")
Exit Function
End If

i = InStr(UCase(dbname), ".ACCDB")
If i < 1 Then
sConnectString = "Driver={Microsoft Access Driver (*.mdb)};Dbq=" & dbname
Else
sConnectString = "Provider=Microsoft.ACE.OLEDB.12.0;Persist Security Info=False;Data Source=" & dbname & ";"
End If

If usrname <> "" Then ' if username provided
sConnectString = sConnectString & ";Uid=" & usrname
End If

If pwd <> "" Then ' if password there
sConnectString = sConnectString & ";Pwd=" & pwd
End If

dba.Open(sConnectString)
Open_Access = True
AccessDatabaseOpenFlag = True
Exit Function
ERR1:
Call Display_Error_Message("Error opening Access DB")
Exit Function
End Function

Here is the error message.
My code also does of verify that the DB is there first.
