vATIS error in XML Document

I have downloaded the latest version of vATIS, but found out that it only supports JSON files. Our ATIS file is a different file type so I am asked to install a legacy version, and I get the error message as the one attached when trying to run vATIS. Hope someone can help.

You can import your legacy profiles as composites into vATIS 4 as described in vATIS for VATSIM

That solved it. Thank you so much!
