SimulIDE closes after selecting a HEX file to load

Hi, I'm trying to load a firmware into a PIC18F452 connected to a LED (image below) and the software closes just after hitting "open" in the load firmware window. The firmware code was compiled using MPLAB X IDE with the XC8 compiler and it's a very simple code to blink the LED every 1 second.

Initially I thought that could be a problem with my HEX file, so I tried to load a different firmware code just to test, and SimulIDE closed anyway, so I don't think the problem is in the HEX file.
I'm using SimulIDE 0.4.14-SR4 and MPLAB X IDE v5.50 (compiler XC8 v2.32).
Is there a way to fix this, maybe I'm doing something wrong?

Hi.

Not sure, but this issue could be already solved.
Try 0.4.15 and let us know if the problem is still there:
