Doesnt run

Downloaded this app and I cannot even register. I have golf shot GPS and it works great. But saw this app and was advertised it should integrate with the other app but I cant even run this app to see if it works. I can log in using my ID on the other app but this app says "cannot login" every time I enter my id. Until this is fixed I cant recommend this app.
