The 4.4.x version of Hippotizer has a lot of changes in it.
You should check your Hippotizer has been cleaned up by uninstalling previous versions and folders before installing any version of V4.4.x.
Important Installation Notes
4.4 introduces significant changes; migrating existing shows from older software will require reprogramming.
- Uninstall all previously installed Hippotizer versions before installing 4.4.
- DMX Personalities have changed — pre-4.4 personalities will not work.
- Component exports are not backwards compatible. Timeline, Presets, Macros and DMX from pre-4.4 cannot be imported to 4.4.
