DVD Architect 2 give error when using subtitles.

[Dentaku]

I have a video which was edited in Vegas 5.
I have added some subtitles in both Korean and English using DVD Architect 2.
I keep getting this error whenever I "prepare" the DVD with the subtitle track turned on:
Warning: An error occured while writing a file.
The sub-picture or menu highlight graphics are too complex and exceed the DVD specification.
I don't get the error if I delete the subtitle track.

The strange thing is that this error has nothing to do with subtitles.

I have tried using no background image and removing all button masks but it doesn't help. The only way it will work is if I remove the subtitles.

I hope I can fix this because I don't wnat to have to add the subtitles by hand and overlay them right onto the actual video file in Vegas (which would solve my problem but be lots of work),

I updated DVD Architect to version 2.0a and it actualyl gave me a useful error message that explained the problem.

It turns outthat my English subtitles where just too big. I split them up into smaller scentences and it doesn't give me the error.
