I used to get that error when trying to export too. I finally gave up and emailed the components to a bud on the forums here and he was able to export it no problem.

I tried uninstalling and installing again, making sure I had up to date Java, you named it I tried it and never got it to work. I haven't used the program since, sorry.

As of this time I still don't think anyone has come up with a fix for this.
