Encore CS3 : "Error: File exists"... veeeeery clear !

Question

I have updated a project in Encore CS3 : cleared old timelines, replaced by updated ones. Remade all links. Checked project before starting the encoding.  While I have been able to do about 5 or 6 versions of this DVD with similar updates, this time, while "building Morion Menus" proceed (Rendering Title menu), at about 80% of the progress bar, it stops and tell me an error box : "File Exists" with the only option to okay ot and stop everything !
Very clear message (as usual with Adobe...) !  I have over 100,000 "files" *existing* on my PC !!!....
Anyone have a clue of what I'v done wrong and what I should correct ?
(Sorry for the frustrated tone here...)
Thanks,
Rob

Answer 1

The only error message that I've ever gotten in Encore was the one above. It was the fourth DVD in a 6 disc set, and I was using a "template" that I had made with only a few Assets (Menus, and common Audio & Video files), plus folder/bin structure. I probably got lazy and did the non-recommended Asset-replacement method, but will never know for sure. While I waited for a response on the forum, I just started over with the virtually empty "template," Imported the Assets, made NO changes to the Assets and everything burned fine. I had probably violated the "cardinal rule of Asset-replacement, without realizing it.
Neil's was is definitely the best.
Good luck,
