Hi Ken,
Sorry to hear that you are running into File corruption. This is sometimes due to the ProAnimator program, or the ProAnimator Preferences getting corrupted.
Try re-installing the ProAnimator plug-in, and also deleting the ProAnimator Preferences file.
To re-install ProAnimator, delete the ProAnimator folder from your After Effects plug-ins folder, and re-extract the ProAnimator zip file you downloaded. Then, move the extracted ProAnimator file into the Plug-ins folder.
To delete the ProAnimator Preferences file, do the following:
1. Find the “/Users//Library/Preferences” folder.
2. Find the “Zaxwerks PA Prefs” file.
3. Delete the Preferences file.
Let me know if you are still running into any issues.
Best,
Edward
