i got error 33 :: 4 [Missing in file] i lost all of my work that i've been doing in a week, ALL of it. how can i fix it?
Well, that's what versioning and backups are for. After a week's work I'd sure have at least five save files - one for every day. That's really your own fault for being sloppy with your data. Otherwise try to import the project into an empty project. Maybe it can recover some of the work. Fir future reference read this:
Even if you didn't make extra saves, After Effects defaults to having auto-save turned on, so try opening your auto save files.
