Mapped drive not showing after installation when adding companies

SOLVED

I have suddenly been getting Error 94 on two PC's.  The rest have no problem. 

I have reinstalled pastel on both machines. Reinstalled pervasive v13.

Followed the checklists to ensure permissions are correct. 

P drive mapped with server name.

When I go into add the companies there is no option for the P drive when I browse. Only the local drive.

The server is in the company database section with a green tick

At the bottom of the Sage registration it shows \\servername\pastel19\custome\registration

I am stumped.  Any help appreciated.
