Unable to connect to selected Mobile Data Service, please try again later

I have my desktop running Microsoft Windows XP Proffesional Version 2002 Service Pack 3.

I have installed both jdk-1_5_0_01-windows-i586-p.exe & jdk-6u16-windows-i586.exe in both C drive & program files since they are a

prerequisite for BlackBerry simulators.

I then downloaded BlackBerry simulators from na.blackberry.com/eng/developers/resources/.
I also downloaded MDS services from na.blackberry.com/eng/developers/browserdev

I downloaded simulators for BlackBerry Pearl 8100 with OS 4.2 and 8800 with OS 4.5.

Then I installed all three of them on a single desktop [2 simulators, a MDS]. During installation there was no error.

I started the MDS and waited till I saw the message "push message sumthin...".
I then started BB simulator 8100 and went to browser. I checked for home page of BlackBerry but of no use,
I got a error message saying "Unable to connect to selected Mobile Data Service, please try again later
If problem persists plesecontact your admininstrator".

I haven't changed anything in the simulator. Also I want to tell that I encounter the same thing with 8800 simulator.

The only thing I would like to highlight is that my desktop run behind a proxy server. So to access internet on simulator what all

changes or settings needs to be taken by me.Internet works fine on my desktop so no issues with network of my desktop.

In the past few days to resolve this issue I visited several forums and I accoring to their advice I carried out following things.

1] Re-installed all the simulators & MDS several times.
2] Checked the version of java installed.
3] Set the PATH in Evnironment Variables in MY COMPUTER -> PROPERTIES -> ADVANCED tab -> & ENVIRONMENT VARIABLES.
4] Meddled with the rimpublic.property file in C:\Program Files\Research In Motion\BlackBerry Email and MDS Services Simulators

4.1.4\MDS\config.

I added these things under the [HTTP HANDLER] section
application.handler.http.proxyEnabled = true
application.handler.http.proxyHost=hostname
application.handler.http.proxyPort=hostport

I also added these under the [HTTP HANDLER] section
application.handler.http.proxyUser=username
application.handler.http.proxyPass=password

So kindly tell me what else do I need to do open any web page on my BB simulator.
