Cannot piloting/running my experiment

URL of experiment:

Description of the problem:
I have bought some credits to allow to run my experiment but since I press the box “piloting” or “running” the message at the bottom right of my screen : “the status is being changed, this may take a few minutes…” appears but lasts a few hours. I can’t then not pilot or run my experiment

thank you

You can’t switch your experiment to piloting because you haven’t yet manged to sync your local files.

I am also having the same issue! My files appear to be synced and I have tried this many times, but no luck.
