Hi Travis,
From our e-mail conversation, you should be up and running with no issues now. If you're running into any other issues, please let me know.
For anyone else running into this issue, there is a compatibility issue with ProAnimator version 4.5.1 and OSX Snow Leopard. To fix this, you can either upgrade to ProAnimator version 5.0.7 or download a specific fix for 4.5.1. For more information on the release of ProAnimator version 5, please visit the link below:
