Executing MS-Access queries to get data in Excel.

Hi Gurus,

I have a problem with the following segment of VBA code which I execute from MS-Excel. In this what I am trying to do is to
1. Open some two queries from a database (in this e.g., it is the sample database Northwind.mdb).
2. Select one of them and select all records in it.
3. Copy & paste it in the current Excel sheet.
4. Close the queries.
5. Close the database.
6. Quit MS-Access.

What is my Problem in this ?
It works fine the first time. But when I rerun the same segment changing my current cell to some other cell in either the same sheet or some other sheet, the code gives an error.
"Run-time error '462': The remote server machine does not exist or is unavailable".
The error comes in the line numbered 6.

1 Sub testopendb3()
2 Dim objAccess as Object
3 set objAccess = GetObject _
4 ("C:\Program Files\Microsoft Office\Office\Samples\Northwind.mdb")
5 objAccess.Visible = true
6 DoCmd.OpenQuery "Category Sales for 1995", , acReadOnly
7 DoCmd.OpenQuery "Current Product List", , acReadOnly
8 DoCmd.SelectObject acQuery, "Category Sales for 1995", false
9 DoCmd.RunCommand acCmdSelectAllRecords
10 DoCmd.RunCommand acCmdCopy
11 ActiveSheet.Paste
12 DoCmd.Close acQuery, "Category Sales for 1995", acSaveNo
13 DoCmd.Close acQuery, "Current Product List", acSaveNo
14 CloseCurrentDatabase
15 Quit acQuitPrompt
16 End Sub

Can somebody out there help ?

Thank you.
