I've read through various threads and tried their solutions, but none have worked so far.
I'm trying to build a BD folder using Encore CC, and I'm getting the error "Blu-ray Object: "short", Export file not found. "short" is the name of a timeline.
At first, I had spaces in my filenames, and I was getting a slightly different error message. Same error, with a different object name.
I renamed all my assets on the disk, relinked them in Encore, and even renamed all my menus and buttons, so now the only characters used are letters, numbers, and underscores.
I deleted everything in the Cache folder.
I have plenty of RAM and disk space. I'm running OS X 10.9.
The "solution" I found is to delete all the assets and re-import them, but that sucks. Some assets contain many chapters, with buttons, end actions, and chapter playlists set up, so it's time-consuming to redo all that work. To minimize the work, I tried deleting/re-importing each asset one at a time, to see if it fixed the problem. Each time, the error message was replaced with a new one, until I had finally replaced all assets.
I think the initial problem was due to spaces in the filename, and apparenlty Encore is incapable of relinking to files with different names.
