I was using after effects when all of a sudden whenever I paused my video the screen goes black. If I hit play I can see my video again but the second I pause it the preview goes black again. Also when paused, if I move the time ruler around I still can't see anything. I have no clue what is causing this and it makes editing basically impossible. The only thing I've noticed is on the composition window it says "wireframe" which isn't on my other projects. Hopefully someone knows what may be wrong.
