Cannot run GA Traffic

Hello all. And a "Happy" Hallowe'en to y'all. I posted this in Marcus Brunner's forum but received no answer. Perhaps someone here can help?Everytime I try to run GA Traffic I get this prompt. It says I have to associate the program w/ this folder. When I try to click "OK" it just keeps popping up and freezes GA Traffic. The only way I can continue is to use the control-alt-delete which brings up the task manager and I have to stop GA Traffic to continue. I can no longer make a BGL file in order to have this excellent program working. I have included a screenshot of the prompt that comes up. Can someone help please?Once again, thank you in advance.
