Nobody can tell you anything without proper system info or other technical details.
Sorry about that. I have a PC running Windows 10-64, 8GB RAM, AMD ATHLON III, NVidia GeForce GTX 750 Graphics Card. I have uninstalled both AE, and PP, and re-installed but still not working. The earlier versions I had prior to this last update seemed to work fine. Should I roll back to a particular release?
