Hello,
Trying on BIAB 2019 to uplaod a super tracks, I've got the following error message :
"This session was made for Aria 1.933 while your version is 1.916. please update!"

BIAB 2019 version is up to date. Any idea about what should I do ?
Thanks for advices

I found the solution there :

As you've found, your Aria engine was out of date. This is not uncommon, especially for those of us also running Finale. I've answered this on the Finale boards many times over the years.

Glad you found it!
