Unable to open .blw file

Just installed sailwave on another computer, but it will not open a *.blw file. The version of sailwave on both machines are the same. 2.29.0
when i try to open the file this is what happens. I have no clue as to what is wrong.

Could not open path\file.blw

Hi Mike,

Can you copy the Sailwave .BLW file to the Document folder of the user you are logged in as on the PC you are having problems opening the file on, then try opening it.

It sounds like a file permission problem to me at the moemnt.
Kind regards,
Huw

Mike,

If you open Sailwave, then open a file via File / Open series - does that work?
