Meida Encoder only renders with comp open in AE and PR?

So my media encoder randomly stopped rendering my videos, except for when it is open in AE and PR. I have to get through a ton of these product review videos and i need to able to work on the next batch of videos while the ones i have done render out in Media Encoder. I have been able to work like this for quite sometime and now randomly my videos (the premiere video part of it, all the stuff i set up in AE still shows fine) are rendered out with the red "Media offline" screen. I'm using dynamic to link my premier>aftereffects>media encoder.
