The -200 is a generic problem during upload error and can be caused by a variety of issues server side or issues with the code. I'm aware of an issue uploading some types of picture files due to an issue with the embedded color profile. If that is your problem, you can switch to use ImageMagick if your server supports it rather than GD2. They said they plan to fix this in an upcoming update.
