Hi Harry,
What you may be running into is if your application lost the file extension. The application should have a file extension of “.app”. If your ProAnimator icon no longer has the file extension, you can try adding the “.app” file extension back.
However, since the standalone is not working, you may want to take this opportunity to upgrade to the newest version of the software. The newest version of ProAnimator released is version 4.5.1. The upgrade is free, so you can continue using your current authorization code. The latest version contains all the latest bug fixes and stability builds.
To download the latest version, please visit our download page below:

You should have no issues with the software after downloading version 4.5.1.
Best,
Edward
