from time to time two errors occured when I wanted to accumulate new respondent data using the "Get Data" button.
The errors are in German and translate to something like: "At least one error has occured" and "Untreated exception in the application. Click continue to ignore the error and continue the application. If you click close, the application will be shut down immediately. The object reference was not assigned to an object instance."
Normally I would just try it again for a few times and it would work after a few attempts. Today I have tried numerous times and did not manage to get the new data. What can I do to solve this problem?
