Hi there,
Can you tell me what version of Flash you are using by clicking "About Flash" in your "Flash" menu?
You can also try installing an older, free version of Keyframe Caddy (1.2.1). https://creative.adobe.com/addons/products/569#.VE_b0YvF_Zg
We have also released a new bug free version of Keyframe Caddy Pro for CC and CC 2014 (1.0.5) https://creative.adobe.com/addons/patches/5166
Let us know if this helps. If you have any further issues, feel free to message us at support@cloudkid.com
Thanks,
-Catie
