The game should really not have any viruses inside, but you can take a look into the "player.log" file located under "C:\Users[your user name]\AppData\LocalLow\Kernis none existing company\Bound in desire"
This is the log file and can be opened with a text editor. Have a look inside and scroll wayyyyy down. Maybe there is some explanation on why it crashed (maybe and exception)
But... well i guess you have to redownload the game again, i mean the exe file is gone for... reasons ??
I am kind of afraid that you have a different virus on your system which slowly corrupts exe files (like that one virus on windows 95), but this is just a wild guess since i am here to program a game and not a virus xD
