Error on access to sql conversion

I know this subject has been beaten to death but I actually have gotten the conversion done and pretty smotthly I must say except for 1 thing, well 1 thing I have found so far.

I am upgrading v6.34 of the forum to sql. Browsing the site it appears to be fine, but when I try to post a new topic it gives me an error as follows:

ADODB.Recordset (0x800A0CB3)
Current Recordset does not support updating. This may be a limitation of the provider, or of the selected locktype.
/forum/post_message.asp, line 277

Now I know this isn't correct because I didn't change the code and locktype is right anyways. Here is the surrounding code to the error.

 'Intialise the ADO recordset object
 Set rsNewTopic = Server.CreateObject("ADODB.Recordset")
 
 'Initalise the SQL string with a query to get the Topic details
 strSQL = "SELECT TOP 1 tblTopic.* FROM tblTopic "
 strSQL = strSQL & "WHERE Forum_ID =" & intForumID & " "
 strSQL = strSQL & "ORDER By tblTopic.Start_date DESC;"
 
 
 'Set the cursor type property of the record set to Dynamic so we can navigate through the record set
 rsNewTopic.CursorType = 2
 
 'Set the Lock Type for the records so that the record set is only locked when it is updated
 rsNewTopic.LockType = 3
 
 'Open the author table
 rsNewTopic.Open strSQL, strCon
 
 'Insert the new topic details in the recordset
 rsNewTopic.AddNew             <--Line 277

So as you can see the code is right, and the driver I am using is the default sql driver that came with the forum.

Anyone, have ideas?
