update: none of my EA compositions will now publish, opening or trying to publish also shows this pair of error messages.
second update: I cannot open this animation at all, just moments after finishing it. trying to open gets an error dialog so long it scrolls off the end of my monitor. i don't know how helpful it is to see this, but here goes.
I’m hoping beyond hope that this is an application error, and that my file isn't ruined. if it is, it means I’ve lost a full week's worth of work. any ideas of how to get this thing going again are very welcome.
I have uninstalled and reinstalled the app, including tossing all preference files. i have also tried downloading the previous version (4.0.1), which also shows the same messages. nothing is working.
never mind. I rescued the composition. I’m not sure, but the the culprit seemed to be saving the file as static HTML. I copy/pasted HTML page components from another document (not saved as static) into a new document, replaced the IDs for this composition, and saved. seems stable thus far.
