Hi, Rob,
This is a forum not customer service. If you want help here, you need to discuss the particular problem you are facing. Did your download not install? What are you seeing that lets you know you have a problem? With that information, you might get the help you need here.
Of course, as you say, you can also give up and try a different program :-). That is up to you.
And of course, it's sad that you got disconnected several times, and I'm guessing you aren't even mentioning how long you were on hold.... All the best of success going forward!
