Ok, it's fixed. I didn't update the version number since it was only there for a few minutes, but if you already downloaded Preview 6, you should download it again. Thanks for the quick notice!
(My apologies for the mixup. I got confused by thinking "zh-TW" mapped to "zh-CHS" instead of "zh-CHT". I should remember this in the future, but just in case, it would help if you post future updates as "Resources.zh-CHT.resx". I'd like to use "zh-TW", but for some reason the .NET Compact Framework will only let me use "zh-CHT".)
Thanks,
