STARDUSTDREAMER'S PROFILE

I downloaded the R-16 version from your website, and two things have come about:

1.) Whenever I try to extract the game from the zip file, and then press "Run" to play it, I get an error message that says "Windows cannot access the specified device, path, or file. You may not have appropriate permission to access the item."

Have I done something wrong, somehow?

And 2.) Norton keeps telling me it isn't a safe file, and removes it. Could this be apart of the reason I can't run the game?
