I have seen this problem mentioned several times in the communities and yet there doesn't seem to be a solution or repair offered by Adobe! I created this complicated presentation yesterday using PE14 (no other version is on my Mac) and had trouble with the "Titles & Text" menu below the time line - it was blank and seemed frozen. So I used "motion title" in the top menu and now I read that it is possibly the reason my project is now incompatible with 14. People have suggested removing preferences which I have done, I have reinstalled PE14, I have opened the app with the opt key down etc. etc. and nothing works. Do you mean my work is totally lost? Has anyone had any luck solving this?
