Already tried changing the path of the POS2NAV, the same error "Invalid JDA File" is still prompting. What I did since the sales audit team have a deadline I copied and pasted the Sales Audit Folder on the Drive C of the RGOC0002  server again Then I changed the PATH file of the Ini folder  of the POS2NAV and Sales Parser on each PC of the users. Then on the server side, I on the sharing tab of the SSI folder then advanced sharing  then add them on full control permission and so I did the same on the security tab. After that I map all their PCs on the network sharing of the SSI Folder to the network Server. This is now done.
