Movie not loaded

[smallcompany]

I have an interactive piece of code that measures Internet connection speed. If I run it locally (from my PC), it works. If I run it from my site, it does not.
Support folks from hosting company run it with no problem. I asked a friend and she run it with no problem too.

In my case, I get the area where SWF should play, in black. Right click onto it shows grayed area “Movie not loaded…”

All is in testing mode. I cannot go out until I get this into “sure” mode that it will run.

I tried it from two PCs (IE6 and IE7, or Firefox), neither would work. Same home network environment for both PCs.

It all points to a client side, but only way for me to get it done is to get it work for me. That will ensure I am on the right path. I tried uninstalling Flash and installing it again, no change. What else I could do?

Thanks
