I'm sharing a file with a client and am using FP 4.3.7. He has some variety of FP 4.1 and is having a lot of issues rendering. I supplied him with my file archive. I have no issues on my end, it renders perfectly. He's getting crashes, memory spikes/leaks, etc. Backburner just won't render it but locally he has some limited success. I'm not exactly sure as I'm not looking over his shoulder but I am trying to help diagnose.
Does anyone know if there would be any issues pertaining to trying to render a file made with FP 4.3.7 in an older 4.1 release?
