I was editing a video an while playing with the scale I went to RAM preview and it wouldn't work so I closed it down and reopened it as this problem has happened a few times and this has been the fix. I then went to RAM preview from the beggining and my computer crashed, no bluescreen the monitors just went blank and the BIOS popped up. I then reopened my project and RAM previewed from the beggining and it didn't start it just said requesting frame 2 of ... I then played with a few of the prefrences eg. clearing the cache and purging memory and It still didn't work. I then disabled multiprocessing and RAM previewing worked again though I would like multiprocessing to work as It is alot faster. I then tried restarting my computer and reinstalling AE but still no luck. Does anybody know a fix for this? Also rendering does not work either with multiprocessing enabled.
