irritating requests to conect to website

I installed a children software program for my daughter – Sesame Street Toddlers by The Learning Company.
Now, each time I boot the computer, the modem dial up box comes in saying “A program is requesting information from www.brodcast.net”.

I click on the cancel button but the box comes in every 5 seconds or so. This is very irritating. It doesn’t help when I click on Connect. The box comes in again the next time I boot up.

The only alternative is to uninstall the whole program, but my daughter likes it.

There must be a hidden instruction somewhere. How do I find it and delete it off?

Regards
Sue
