Yes
now it is visible, Kimsiang85. Please add a 0.1uF cap between Vdd and Ground, close to the F877 power pins. also, try one across the pins 1&2 of the display. Generally as you don't read from the Display, they used to permanently keep in write mode, if I am correct. Nothing wrong if you want to manage it from software, perhaps.
BTW, can't you try whether you can recover earlier versions of software, as it would help to know up to what level it has worked, before the present condition. May be you may have them as backup files.
For future,it would be a good practice, to change the file name by adding another digit at the end and then save.
