Could you try these steps:
Try authorizing it in Settings -> Privacy & Security.
If that doesn't work, you can try openning a terminal (command + space, type in terminal, hit enter), then run:
chmod +x PATH TO APP.app/Contents/MacOS/LustsCupid.app
Once you've done that, you can try again to do the usual Settings -> Privacy & Security.
