Importing Notepad file

I am trying without any success to import a notepad file to MathCAD.

I am trying through Insert componenents / Read from ,etc, but alweays get the message

No data was found in the specified file.

the file is populated with figures, I attach an extract.
I am sure this worked before for me.

I have been unsuccessfull evn with READPRN.

Any advice would be very welcome

Best Regards
