I just bought Zaxworks 3D flags for AE. Running on a macbook Pro.
The software is great and looks good, but I am currently on the temporary key as I only bought it a few hours ago. However when ever I try to render, either a sequence or a frame, a box pops up in the background warning me that it is a temp key that will only work for 30 days. This is fine but there is no way I can press OK or Register in the box. So AE then does nothing. Until I force crash it is unusable.
Unfortunately I have an urgent deadline and can now not even render.
Try registering on our web site to get the authorization code, or if you need the code urgently, please give us a call and we will provide you with your permanent key. I'm not sure why you are unable to press the "OK" or "Register" buttons, but once you get the permanent code, create a new After Effects project, and apply 3D Flag. Then, try entering the permanent authorization code, and you should be good to go.
If you're still running into issues, please let me know.
