Questionnaire level data missing


we are in the middle of a survey, and have previously created, our assignment files for all our assignments we have been using this fills for batch upload purposes over the last month and a half however upon trying to upload new interviewer assignments, we started receiving this error. “PL0040: File with questionnaire level data is missing.” which is strange as we haven’t had this error previously using the same files and the files has not been changed.
Please assist thank you.

This is an issue introduced in latest release, it will be fixed soon. Meanwhile, you can workaround it by using advanced preloading.
