Get Rid of Workgroup setting in LibreOffice

I am trying to use LibreOffice word to get to my files created in WordPerfect that are in a subDirectory on the C:\ drive.

LibreOffice keeps demanding that I sign in with a password in a user group. I am not USER GROUP. How can I get rid of this so I can just click down to and get my files into libreOffice so I can learn to use it in my Ubuntu 18.4 Linux?
