MPLAB simulator problem

Hi folks so to start - I program in assembler, use MPLAB X 5.35 and MPASM.

Ok this problem has just occurred and I cannot work out what is happening!

Last week I was simulating some code on a PIC12f1822 and everything ran fine. Yesterday I starting working on code for a 16F1825 but when I come to simulate this morning the code gets to the line beyond org 0 and stops.

When I open last week's project it does the same thing too!

Tried re-installing (although not removing first MPLAB and the same problem.

The simulator works for a 16f688 just not the too above, but there have not been issues when simulating previously!

Can anyone shed any light please?

Not sure if you tried this. You may want to go in and delete all the intermediate compilation files. I have found sometimes they get corrupted.
