Using BIAB 2012, build 349. (just arrived yesterday)

As I have used BIAB since the DOS days, I still have many songs with short file names.

There is fortunately, a feature in BIAB to bulk rename all the short file names to long ones, based on the title of the song.

However, it doesn't work for me. I keep getting the error message:

"Unable to rename file---***(filename)
Perhaps this title is not unique."

I click OK, and then the error message pops up again, with a different song title. It keeps occurring one after the other, could go on for hours pressing OK, with nothing being renamed. I don't see a way to cancel out of it though. It looks like I will have to go to the Windows Task Manager, to forcibly end BIAB, in order to end this procedure.

Why is this happening?
