Thanks for that Steve.

Did not realise it was that long since I updated my MPlab.

It now compiles after installing Mplab 7.21.

Get a bunch of warnings which is interesting:

**
For the PIC18 devices, the __CONFIG directive has been superseded by the CONFIG directive.
**

But it still compiles so must still have the old settings still in there and the fuses show correct when loaded into the programmer software.

At the end of the day I am going to use a Bootloader anywayz and so config settings should not matter in theory as they will be set when Bootloader is programmed.

Many thanks again

Regards

Sean.
