After Effects problem with .fla

[sebisaia]

Hi,

For a screencast e-learning formation I have to show the new .fla possibility in After Effects 2019.

I have tried it in january with succes but today that doesn't work probably because of a bad dynamic link connexion...

Is this problem known and have you an issue for me to solve it ?...

Thank's

Sébastien
