I don't see where you open your connection.

You need objConn.Open <connection string> somewhere in your code.

Here's the correct code:
=======================================================

<%Option Explicit
Response.Expires = -1

dim objConn, objRS, strSQL, strConn
dim strUsername, strPassword, strIP, strPrepay
dim blAlreadyLoggedIn

'open connection
strConn = "PROVIDER=MICROSOFT.JET.OLEDB.4.0;DATA SOURCE=/DB/CCDB.mdb"
Set objConn = Server.CreateObject("ADODB.Connection")
objConn.open strConn

'get ip address
strIP = Request.ServerVariables("REMOTE_ADDR")


Private Function CheckSessionClearing()
   
    strSQL = "Select * from tblSession where IP='" & strIP & "' AND Payed = NO;"
    Set objRS = objConn.Execute (strSQL)
    If objRS.EOF then CheckSessionClearing = True
    set objRS = Nothing
   
End Function

Private Sub UpdateSession()

    strSQL="INSERT INTO tblSession (IP, Username, StartTime) VALUES ('" & strIP &"', '" & strUsername
&"', '" & now() & "');"
    objConn.Execute (strSQL)
   
End Sub

Private Function CheckUser()

    strSQL = "Select Username,MinutesLeft From tblMembers Where Username = '" & strUsername & "' AND
Password= '" & strPassword & "';"
    Set objRS = objConn.Execute (strSQL)
    If Not objRS.EOF then
         strPrepay = objRS("MinutesLeft")
         if strPrepay = "" or strPrepay = "1" then strPrepay = 0
         CheckUser = True
    End If
    Set objRs = Nothing
   
End Function
%>


======================================================
You were missing a couple of "()" too.

Try this. I added replace function for strings in sql statements to prevent syntax error if the value contains single quotes.

<%Option Explicit
Response.Expires = -1

dim objConn, objRS, strSQL, strConn
dim strUsername, strPassword, strIP, strPrepay
dim blAlreadyLoggedIn

strConn = "PROVIDER=MICROSOFT.JET.OLEDB.4.0;DATA SOURCE=/DB/CCDB.mdb"
Set objConn = Server.CreateObject("ADODB.Connection")
objConn.Open strConn
strIP = Request.ServerVariables("REMOTE_ADDR")

Private Function CheckSessionClearing()
   
    strSQL = "Select * from tblSession where IP='" & replace(strIP, "'", "''") & "' AND Payed = NO;"
    Set objRS = objConn.Execute(strSQL)
    If objRS.EOF then CheckSessionClearing = True
    set objRS = Nothing
   
End Function

Private Sub UpdateSession()

    strSQL="INSERT INTO tblSession (IP, Username, StartTime) VALUES ('" & replace(strIP, "'", "''") & "', '" & replace(strUsername, "'", "''") & "', '" & now() & "');"
    objConn.Execute strSQL
   
End Sub

Private Function CheckUser()

    strSQL = "Select Username,MinutesLeft From tblMembers Where Username = '" & replace(strUsername, "'", "''") & "' AND Password = '" & replace(strPassword, "'", "''") & "';"
    Set objRS = objConn.Execute(strConn)
    If Not objRS.EOF then
         strPrepay = objRS("MinutesLeft")
         if strPrepay = "" or strPrepay = "1" then strPrepay = 0
         CheckUser = True
    End If
    Set objRs = Nothing
   
End Function
%>

<HTML>
<BODY>

<%

If CheckSessionClearing = True then
    If Request.Querystring("Username") = "" then
         strUsername = Request.Form("txtLogin")
         strPassword = Request.Form("txtPassword")
    else
         strUsername = "Cyberguest"
         strPassword = "Cyberguest"
    end if
    If CheckUser = True then
         UpdateSession
         Response.Write("STATUS=OK*USERNAME=" & strUsername & "*PREPAY=" & strPrepay & "*START=" & now() & "*")
    Else
         Response.Write "The username or password you entered is incorrect.<BR><A href=login.htm>Try Again</a>"
    End if
Else
    Response.write "Sorry but an existing session has not yet been cleared. Please contact a member of staff"
