LaunchCast player window is always closed.

Used to be able to listen to music on LaunchCast. Now I cannot even get the
player window to remain on screen. When I launch "My Station" the player
window is launched and then some program kills it but I am finding it hard to
determine which program is doing this.

I have disabled the Pop-Up blocker both in ZoneAlarm Pro and IE ,
un-installed PopUpKiller and both the REALBAR and Yahoo Bar, checked in
SpywareBlaster (nothing obvious there - unless it has a different name),
SpyBot and AVG but I can't see which application is stopping the window from
being launched.

I have used BELARC advisor to view what is running on the PC but there seems
to be nothing there even though I know it is there...somewhere!!

Help!

Previously I was getting the message:
"Error
Sorry, could not load all required files. Please try again later.
Error Code: 27 - playerWindow.js"

Now the window just keeps getting "terminated".

Your assistance appreciated.
Thanks

Well, I have un-installed SP2, Sun Java Runtime and rolled back WMP to WMP9.

The player window was still getting closed. I decided to switch to another
location (country) of LaunchCast and try...you'd never believe but now the
player window comes up and REMAINS. That's the good news.

The BAD news is that now I'm back to the error "... Sorry, could not load
all required files. Please try again later. Error Code: 27 - playerWindow.js"

I tried registering the wmp.dll as suggested at
http://www.zachd.com/pss/pss.html#launchcast
but still get the error.

Any ideas/fixes welcome. Failing that maybe I'll need to install XP again
on top of the current installation and hope it resolves the issue....
