I have been running X12-ARIMA in NumXL every day for months on the same series (with a few new added values every day) with no problem. Today, however, no seasonal adjustments are working at all! All series are broken, I have attached one for illustration. Please help in solving this urgently as I rely on using it daily in my work.
I am not aware of any updates, changed settings or otherwise on my computer and it worked fine yesterday. Whenever I go through the wizard I can only do "apply" but the Run X12-A does not light up. So of course the formula does not work when called by X12acomp etc.
I tried rebooting, removing the add-ins, uninstalling it, installing the latest version, and activating the add-in again in excel.
