Layers not showing in comps, on error (17 :: 19)

After Effects keeps showing the infamous error: overflow converting ratio denominators. (17 :: 19) when I

open a some comps in my project to edit them, and after the error message the comps seems like they were empty, but the layers are there, since when I hit play the animation shows up. There is no video file in any of those comps so no, there is no

frame rate issue. There are just a bunch of photoshop layers with simple animations, some masks and so, but none of them is hidden (shy)... so I'm kind of frustrated with the situation. I even tried opening older versions of the project but the error persists. Please help!!
