OK, here goes:
'Declare connection...
Dim objConn
Set objConn = Server.CreateObject("ADODB.Connection"

objConn.ConnectionString = "DRIVER={Microsoft Access Driver (*.mdb)}; " & "DBQ=" & Request.ServerVariables("APPL_PHYSICAL_PATH"

& "WebForum\User_Accounts.mdb"
objConn.Open
'Declare recordset object...
Dim objRS
Set objRS = Server.CreateObject("ADODB.Recordset"
'Declare SQL query.
Dim strSQL
strSQL = "SELECT * FROM tblUsers WHERE UserID=" & Request.QueryString("UserID"
'Open the database and get the requested info!
objRS.Open strSQL, objConn, , adLockOptimistic
objRS.MoveFirst
objRS.Delete
objRS.Close
Set objRS = Nothing
objConn.Close
Set objConn = Nothing

As I said: it works with another application that works the same way, but now it just doesn't!
And yes, - all files are in the directories were they should be, etc...
thanx!
