error "Bizagi error Timeout error occurred loading the page"

I have been facing problems when trying to open files in bizagi where it shows the error "Bizagi error There was a timeout error while loading the page". I have my free account and I always had the opportunity in other versions to be able to record local files, as it was not mandatory to use the cloud space. I am currently using version Do you know why this error? And how can I manage (delete) files up to 10 megs because I only see the group save function.

What are the restrictions between free and paid license. Could you send me the values ​​and restrictions please?
