NHibernate profiler doesnt fetch my sessions - nhibernate

Question

I've just downloaded nhibernate profiler and I cannot figure why it is not working.
As far as I know, it should be enough to set Connection string inside Options - Edit default connection.
I'm using sql server and I've copied my connection string like this
Data Source=.\SQLEXPRESS;Initial Catalog=DB_xxx_MyDb;Integrated Security=True;
In debug mode of my app I have nothing inside nhibernate profiler when executing my app.
Update:
Added reference to my mvc3 project
HibernatingRhinos.Profiler.Appender.v4.0.dll
Global.asax
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
RegisterGlobalFilters(GlobalFilters.Filters);
RegisterRoutes(RouteTable.Routes);
#if DEBUG
HibernatingRhinos.Profiler.Appender.NHibernate.NHibernateProfiler.Initialize();
#endif
}
I made following steps
start NhProf.exe
start debugging mvc app, these app queries I want to profile
Nothing appears in Nhibernate profiler. Licence is working for 32 days.
Why? What else should I do?
Second update:
I tried with reference HibernatingRhinos.Profiler.Appender.dll still no working.
Tried with options-settings-listen port to set my asp dev. server port, right now is 5442.
Still nothing. I'm bit confused.
Just to mention that my app works, my connection string works, I am able to fetch data from my db, ...
My log.txt file inside NHProfiler folder have this content

Answer 1

Have you initialized the NHibernateProfiler in your app/websites?
Something like this in the Applicattion_Start() or Main()
#if DEBUG
HibernatingRhinos.Profiler.Appender.NHibernate.NHibernateProfiler.Initialize();
#endif
Also remember to reference the dll
HibernatingRhinos.Profiler.Appender.v4.0.dll

After returning default listening port inside options-settings everything works. Finally. Thanks #Iridio.
Btw if anyone needs to conclude:
Step 1: Add reference
Step 2: Inside Global.asax Application_Start() add these line
#if DEBUG
HibernatingRhinos.Profiler.Appender.NHibernate.NHibernateProfiler.Initialize();
#endif
Step 3: Start NhProf, inside Options-Connection string add your conn.string.
Step 4: Run your app.
The default listening port is 22897. Do not change this.
