When I try to log on to NavyField, I pick my server and hit enter/log in and the message
box says Data File corrupted and dose not let me log in. NF use to work on my laptop but I
had to download it and re-install and now I can not log on anymore. I am going to
reinstall it again and see if that fixes it.

I reinstalled it and same thing, now to re download it from a different source.
