Export PNG sequence from CH fail

Hi there!

I tried to export a PNG sequence from my project in Character Animator but I'm thinking it isn't working because at the end of the process all I get is one .xml, one png file called name of the project_4423.png, one .json file and a wav file with nothing in it. Even so, I tried to import this PNG file in After Effects but all I got was one blank frame and nothing else.

My project is kind of big. I have 6 characters playing a song. It's a band composed by a lead singer, a drummer, a guitar player, a bass player, a xylophone player and a cat. The whole thing is 02;27 minutes long.

I also tried the Dynamic link but that didn't work as well. After a while I got a prompt from AE telling me it couldn't establish a link with the dynamic server.

Can someone out there point what I'm doing wrong? I'm novice at this, until now I only exported my CH porojects via Media Encoder. Thanks!
