Footage from Premiere showing grey in after effects

[becausemic]

I have been editing this clip for a while now and all of a sudden all the footage from premiere has gone grey/black, the footage has fully loaded and I have hardware acceleration on. The masks from the said clip are appearing but without the footage in them! When attempting to render the footage using adobe media encoder it results in "failed". I hope the community can help me solve this problem, thank you!

Update: Weird, but troubleshooting myself, when "Editing original" of said premiere file the footage reappears as I have premiere open at the same time???

Update: I am still having the trouble renderring/exporting and the premiere footage continues to go grey on occasion

Simple answer: Straighten out your hardware-acceleration stuff. Check the relevant settings in all programs, update your graphics drivers, revert to software-only rendering modes, buy a new, more powerful graphics card. Whatever gets the job done.
