Thanks for the prompt response Paul. I suspected what you have mentioned 
below. Just got a new Dell Laptop and have been asked by the local radio 
clubs here to do some satellite presentations, so I have been attempting 
to install all the various satellite programs I can find or already have 
to show what is available. The system is off now so I'll have to check 
it later, but I suspect that it is an old version of 1.0. I don't 
remember having upgraded since I went to Wisp, Winorbit and others.
