From where are you opening the file now?
Through that welcome screen on ID.
I click open, then navigate all the way to the file folder, and open it.
Is this from the packaged folder or the old location? Type 1 fonts don't work on Windows in the Document Fonts folder, if I remember correctly. If ,in fact you are trying to open from a package, try renaming the Document Fonts folder to anything else and see if it makes a difference.
My original document is fine... no pink alerts.
If I pack the document, change the "document fonts" name for anything else and try to open the packed ID file, I get that missing font dialog box.
If I change it back to the correct name, it opens fine (no missing fonts alerts), UNTIL, I get a ID crash... When I try to reopen the same file after the crash, I get that missing font screen.
Any other hint?
Sounds like maybe one of the fonts is damaged, but hard to tell
