To keep everyone the loop, there are multiple issues on @lauren_gubler machine:

1. She was not able to update ProSeries. As a result she was unable to efile. We resolve the issue by re-run the Setup.exe from ProNet20\wkstn

2. After the update, all records in the Homebase are getting duplicated, we removed the c:\prowin20\homebase\hb.db files, and re-ran Homebase Maintenance to fix the duplication

3. After that her Homebase was back to normal, and she was able to efile it her working return successfully.
