limit to the number of blocks in a project

Hi, but there is a limit to the number of blocks in a project? For several days when loading the project I get this message (see attachment)

"It appears that SCREEN has had all blocks removed. Either you removed them intentionally, or this is the result of a bug in our system."

If I continue, the system deletes all blocks present in SCREEN

Why?

what happens, if you click "No, Don't save"?

the system load the project again but at 99% the same message reappears

Your best bet would be to load the project back into AI2 from the AIA backup file you made.  You HAVE been making backup files, right?

Hello. I tried to reload the backup but the message appears the same. I tried again now so normal and loaded without problems. I hope this was just a server overload.

Now everything is clear. You are the best

Aw shucks ;)!
