Wheres the Support

Used the free version and it worked great. When I purchased the upgrade, it didnt work. DirectTV said they didnt provide the app, it was a third-party developer. I looked up the developer, RMR Labz LLC, but cant find any tech support except a troubleshooting list that doesnt solve the issue. HELP! How do I fix it or get my money back?
