Yes, okay, I'll try to describe it.
I boot up my computer, then open toribash and play for a bit, close it as I don't feel like playing any more at the moment, then do other stuff, then I click on the shortcut again, and it dosen't open no matter what I do, even go to the program files folder and try the toribash there, nothing, and also, when I click on it, it has the mouse with the loading icon, but it just goes for a second, then dissapears, and no window pops up.
It's even there in the processes tab on the task manager, but not on the applications tab.
So sometimes I reinstall it, and it dosen't even open, I just gotta reboot to play again.
This wasn't happening a week ago, and now it does, I haven't changed ANY of my hardware, harddrive, or anything. Can anyone help me find a solution?

Show us the stderr.txt please.

It's empty, is that bad?
I never touched the file.

Kill the process after you close the game.
