The first one sounds like there may be an issue with character encoding, maybe from the stimuli you’re using. I ran into an issue with using HTML codes in my sentence stimuli and the parser was unable to get past the code, so I had to remove all the HTML from the output (a pain) and then it parsed fine. I had to use HTML to show apostrophes in sentence stimuli (because Qualtrics wouldn’t display any sentences with apostrophes) which then caused the parser to crash (argh!).
There is another thread above talking about problems with quote marks – maybe that’s the same issue you have? Or maybe you can explain what your stimuli is?
As for the init error, I haven’t seen that one before so don’t know of any solution 🙁
