I have several backups of the Mailstore home folder on my USB drive, I am getting an error when trying to go back and open them... attached is the full error report. Any help would be appreciated as I have several of these (these could be from a previous computer possibly or at least another Windows install if that matters)

I may have solved this, I was able to open one of the archives by running the config program as administrator before opening the folder.
