Game Project went "Into the darkness"

I'm a bit pissed off today. I was working on my game normally, i was refining it a bit more on map decoration and lighting.
Little did i know that my laptop's charger was not connected correctly, the plug came off!
i didn't notice that the laptop had low battery the laptop was executing the RPG MAKER program.

My PC suddenly went off and i looked around it and saw my charger's plug was not in properly.
So i turned on my PC normally and opened my project back up, i knew i saved my current progress because i play-test my game when i have something really doubtful or have something that i need to see.

to my surprise i got this small error.

Now i didn't know what happened and thought that it was a stupid error of the program.
so i launched again. Same error.
I decided to re-install the game engine. Nothing new apparently. I went online and i am not the only one with this error.
I found some solutions but did not help me at all.
The only thing i got is the backup which is pretty much old.
I've lost about 90% of progress here and i am seriously pissed off that a "professional" game engine does this to you.

For those who wanted to play Into the Darkness will have to wait. In other words, the game has been "Delayed" for further notice.
