I work for weeks on the same ae project and saved the file yery carefully and regularly. All of a sudden I can't open my project anymore...
After Effects sends out the Warning: "File cannot be imported as project (defect format or not readable)". So what can I do? That is a real damn problem....
Thanks for your help in advance!
All the best,
Did you have Auto Save active? Try opening an earlier version of the project from your Auto Save folder.
Hopefully you use some kind of backup regime: Adobe's Cloud services, Dropbox, Apple Time Machine etc.
If not, try creating a new project and importing the old project into it - this sometimes works.
Did anything that Andrew suggest work for you? Sure hope so. Please let us know.
