Help. Sony support won't answer my emails, so I'm hoping someone here can help me. I have movie studio platinum. Its behavior is odd. I once could make a 3 minute 4k video in about 3-6 hours, now it is taking over 24 hours. CPU only reaching 25% during renders. I have F-disc and reinstalled OS, reinstalled platinum in hope of getting back to where it was. Problem seems to be getting worse. No help from sony, I don't think they're reading my emails. I'm at the point of tears, this is aweful.
