My gut feeling was wrong. It was only that a single f'ing menu was corrupt (the one that was open when the program crashed). I was able to open the file and can now continue working on it. Luckily, you can order files by last modified in Windows, so I located it quickly. Photoshop couldn't even open it.
I have no idea when this will be completed, or if Encore can even compile a disc this complex, but I will somehow get the set out soon. There may be more swearing on the horizon, but at least in Encore the disc is looking superb!
