Problem With QN Subscription

Hello, I have spend 2 days already in search how to fix my query notification problem. Here is the case :

I run very very basic query like "SELECT name FROM dbo.author" with SqlNotificationRequest and I monitor events in SQL profiler. On Audit login I have :

-- network protocol: TCP/IP
set quoted_identifier on
set arithabort on
set numeric_roundabort off
set ansi_warnings on
set ansi_padding on
set ansi_nulls on
set concat_null_yields_null on
set cursor_close_on_commit off
set implicit_transactions off
set language us_english
set dateformat mdy
set datefirst 7
set transaction isolation level read committed

Later on QN: subscription :

<qnev:QNEvent xmlns:qnev="http://schemas.microsoft.com/SQL/Notifications/QueryNotificationProfiler"><qnev:EventText>subscription
fired</qnev:EventText><qnevubscriptionID>0</qnevubscriptionID><qnev:NotificationMsg>&lt;qn:QueryNotification
xmlns:qn="http://schemas.microsoft.com/SQL/Notifications/QueryNotification" id="0" type="subscribe" source="statement" info="set
options" database_id="0"
sid="0x797D7BA77E16734CBD078C0792036845"&gt;&lt;qn:Message&gt;a3624325-79cd-4548-b7e8-92f2939e3696&lt;/qn:Message&gt;&lt;/qn:QueryNotification&gt;</qnev:NotificationMsg><qnev:BrokerDlg>69F126A0-BDA8-DC11-BAAC-000FEAE5BBF8</qnev:BrokerDlg></qnev:QNEvent>

I understand my subscription fails but the reason as given in msdn is :

"The connection options were not set appropriately when the command was submitted"

You can see that my options are exactly as stated in MSDN. I'm stuck here and don't know what more to check in order to resolve this. If anyone can point me in some direction what I can check for this error will be highly appreciated. Thx in advance
