Server Error: could not upload project. Please try again later


Anyone knows how to solve this?
With appybuilder offline version of 1 august, it have worked right.
Then i actualized it (with tortoise git) and know i get this problem when i trying to upload a aia file…

Any clue on how to solve it with appybuilder or how to get back to the old version? (i used pull option to actualize it)
