I can't open ProSeries 2020. I receive an Error Message "Index was outside the bound of the array". I can open other years, but not the 2020 version. I can't find any help online for the issue as it relates to ProSeries. I have gone through two customer service reps and also spoke to Microsoft (windows operation system) but the issue is still not resolved.

I have uninstalled, rebooted, to no avail. Any help is appreciated.
