Text dissapeared from documents after recent update

[#1]

I updated to the latest version of illustrator yesterday. I have just opened a document that I am working on and even though the preview shows all of the text in place, when I open in illustrator, all text is missing and there are no missing font warnings. Can somebody help please.
